...A chemical reaction is where two or more substances come together and pops, fizzes, and in some cases explode! Alka Seltzer is a type of chemical reaction where you put water and carbon dioxide gas. Equation . When Alka-Seltzer tablets are dissolved in water, bicarbonate forms (from the sodium bicarbonate), which in turn reacts with hydrogen (from citric acid) to form water and carbon dioxide gas. “ In The bicarbonate reaction project you will find out for yourself by plopping Alkaseltzer tablets into water at different temperatures, and timing how long it ta of the bicarbonate reaction? In thiS how is temperature related to this bicarbonate reaction? In order for the reaction shown above to occur, the bicarbonate ions have to come into contact with the hydrogen ions.” Molecules in a solution are in constant motion, and are constantly colliding with one another. The hydrogen and bicarbonate ions must collide at the right angle and with enough energy for the reaction to occur. The temperature of a solution is a measure of the average motion (kinetic energy) of the molecules in the solution. The higher the temperature, the...

...reactants in this experiment were distilled water and Alka-Seltzer tablets. Water contains H2O, and the ingredients in Alka-Seltzer are aspirin, citric acid, and sodium bicarbonate (NaHCO3). When sodium bicarbonate is placed in water, it dissociates into sodium (Na) and Bicarbonate (HCO3). When the bicarbonate splits apart, it reacts with the hydrogen ions from the citric acid. This forms carbon dioxide and water. When Alka-Seltzer and water react; it forms Carbon Dioxide Gas. The reactions forms when small bubbles form, and fizzing occurs. This must be visible to the eye, and the fizzing must also be heard. Increasing or decreasing the number of Alka-Seltzer tablets did change the...

...The effects on heart rate on a Daphnia Magna with varied substances William Piper WCCC/Spring 2015 Semester A&P 2 Dr. Sisak Introduction: The purpose of the experiment conducted was to test the effects of varied substances on the heart rate of a Daphnia Magna. A Daphnia Magna is a freshwater flea native to North America (Wikipedia, 2015). The substances used on the Daphnia were aspirin, nasal spray, Alka-Seltzer, coffee, and tea. Aspirin is a common pain reliever and fever reducer (Rx List, 2015). Pain increases heart rate; therefore, a pain reliever would inherently reduce the heart rate of an organism (Storella, 1998). Nasal spray works by constricting blood vessels in the nose to help reduce swelling and inflammation to...

...William Fort Mrs. Chambers Honors Biology, Period 3 31 August 2016 Alka-Seltzer Lab I. Abstract: In the lab, four Alka-Seltzer tablets were dropped into 150 mL beakers of water at four different temperatures. After the time it took for each tablet to dissolve was recorded, a clear trend was revealed within the data. This trend demonstrated that the water’s temperature corresponded with the rate of which the tablet dissolved; if the water’s temperature was warmer, the Alka-Seltzer would dissolve more quickly. The quickest trial, in 90°C water, took only 20.75 seconds for the tablet to dissolve, compared the longest, in 15°C water, which took 36.65 seconds. This data is applicable to the real world, giving this study scientific importance....

...have at least one of these ingredients: aluminum, Calcium, magnesium, and sodium ( Directly on the back of the products). The aim of this experiment was to evaluate and test the effectiveness of antacids. Hypothesis: All antacid will not be equally effective because they all have different ingredients. Introduction: Within this experiment, the three different antacids was chosen: Maalox, Rolaids, and Tums. To get started we had to crush one antacid and add it to 100 ml of distilled water in a beaker. We did all three antacids separately, but made sure that all three antacids dissolved properly, meaning you don't see some on the bottom of the beaker. By using a stirring rod, stirring can help dissolve the antacids. We had to transfer the three different antacids into three separate test tubes with a pipet adding 5 mL of antacids solution. When we done this we then had to add 4 drops of bromcresol purple to the test tube. Bromcresol purple is a pH indicator. Then we had to add 0.1 M hydrochloric acid to the three test tubes, we had to mix after every drop. this was repeated until we say the solution turn yellow. which indicated an acid occur. Each antacid had different numbers of drops to turn yellow. we recording it in our chart. Antacids Active Ingredient # Drops of HCL Added | Alka Seltzer | NaHCO3 | 130 | Tums | CaCo3 | 63 | Rolaids | Mg(OH)2 | 36 | Maalox | Al(OH)3 | 4 | (Table 1) By...

...The Effect of Alka Seltzer on Water Background Information Alka Seltzer can be used as a pain reliever and an antacid. Baking soda or sodium bicarbonate is the active ingredient in antacids. Citric acid is also used in antacids, providing hydrogen ions. When antacid tablets are dissolved in water, they produce bubbles, or carbon dioxide. Sodium bicarbonate splits apart to form bicarbonate and sodium ions. Bicarbonate ions then react with hydrogen ions to form carbon dioxide gas and water. For the reaction to happen, the bicarbonate and hydrogen ions must come into contact with each other. The contact is affected by the temperature. The higher the temperature, the faster the molecules move. In cold conditions, the molecules move at a slower...

...Alka-Seltzer tablets are little flat circles that, when placed in water, fizz. These tablets are used for relief of headaches, pain, heartburn, indigestion, and many more. The tablets fizz in water because the sodium bicarbonate and citric acid in the tablets are reacting and producing carbon dioxide bubbles. In our lab we tested the affect of different temperatures and acidity levels of water on the speed of the reaction of the Alka-Seltzer tablet. My hypothesis for the lab on how different temperatures or amounts of acid affect the reaction time of Alka-Seltzer tablets was, "If Alka-Seltzer reaction is related to temperature or acidity of water, then the warmer the water the faster the reaction." I support this hypothesis because when looking...

...Chemistry is one of the most fundamental sciences of them all. The precious bonds of atoms hold together all life and all that support it. A good example of how chemical bonds and the reactions that forge said bonds is the reaction of Alka-Seltzer® tablets placed in water. People use these tablets to relieve pain. Which leads to the question; “Does the size of a particle have any affect on the time it takes for a reaction to complete?”. Alka-Seltzer® contain three key ingredients sodium bicarbonate, aspirin, and citric acid. A key component of Alka-Seltzer® tablets is the sodium bicarbonate, known in the chemistry world as NaHCO₃. When sodium breaks down in water, the reaction forms sodium ions and bicarbonate ions, which then breaks down...

...A solid broken down into powder has the largest surface area, because it is broken into smaller particles and each of those particles has its own surface area. This increases the overall surface area. (BBC, 2014) This is why catalysts are often used in the form of powder. Hydrochloric acid or HCl is a strong acid that reacts against the Alka-Seltzer tablets during this experiment. The Alka-Seltzer tablet’s main component is sodium bicarbonate, also known as baking soda, having a chemical formula called NaHCO3. Because Alka-Seltzer tablets are carbonates, they react with strong acids like HCl to form compounds that are different chemical composition than the initial compounds. This is known as undergoing a chemical reaction. Other carbonates like calcium carbonate produce similar reactions. When adding Vitamin C tablets to hydrochloric acid, it initiates a chemical reaction called a double displacement reaction. For this reaction, the ion of one compound exchanges with the ion in another compound following the general formula: AB+XY forms AY+XB....

...placed on top of the test tube’s gas delivery tube. The well plate with the test tube was placed in the tin while the gas displaced some of the water. When the water in the pipette was completely replaced by the gas I quickly removed it and placed my finger over the opening to prevent any gas from escaping. I lit a match and gently squeezed out some of the gas and observed and recorded the reaction. I then took a marker and marked 3 equal parts on the pipette. The pipette was again filled with water and placed on the gas generation tube like previously. When the bulb was 2/3 filled with gas it was removed and placed in a well with the opening done to be used later in the experiment. The test tube was taken apart and the items disposed of properly. The test tube was thoroughly cleaned for the next experiment. Oxygen: A few pieces of Mn were placed into a clean test tube then I added hydrogen peroxide to fill the test tube leaving only 1 cm open at the top. The rubber...

...strong acid within the stomach known as hydrochloric acid (HCl). HCl is essential as the body uses it to digest the food that comes in. Through this process is how humans can break down all the food eaten to take in the nutrients necessary for survival. The pH balance within the stomach can be disrupted depending on which foods the person chooses to consume. People can also have genetic predispositions to easily upsetting the pH balance within their stomach (Madell, 2012). At an average of a pH 3, the stomach may fall below that level and cause uncomfortable symptoms for which pharmaceutical companies created the antacid. The purpose of antacids is to neutralize stomach acids. An example of such an antacid would be the brands Tums or Alka-Seltzer. There are many other brands that provide acid indigestion relief to customers but there is always one that has a better record at relieving symptoms quicker and stronger. To determine which of four brands neutralizes the drop in pH in the stomach best, a titration technique was used. Phenolphthalein was used as an indicator because of its correlation of color change with pH level. In basic conditions, it is pink and as soon as it becomes acidic it turns clear. The goal was to find the lightest shade of pink which indicates it is right past the neutral point. Using this data, we can find which antacid could provide the best neutralizing effect. Finding out which antacid works better allows for the consumer to know where to allocate...

...Effectiveness of Antacid Tablets by Trisha Dwivdi, 2002 Abstract The purpose of this project was to figure out if antacid tablets are effective in neutralizing the human stomach. Effective was defined to mean that the tablet did not neutralize too much of the solution or too little of the solution compared to other brands. I titrated a solution that had a pH that was similar to the human stomach and tested four brands of popular antacid tablets. The four brands were Pepcid AC®, Zantac 75®, Rolaids®, and Alka Seltzer®. Rolaids® was the only brand that did not neutralize the solution. The other three antacid tablets did work and I decided that antacid tablets are effective in neutralizing the human stomach since they did not neutralize all of the stomach solution or they did not just neutralize a small amount of it. This experiment was all relative to the other tablets, because I had no background information on what defines an antacid tablet to be effective so I had to base it on the results of the other tablets. Rolaids® took an irregular amount of stomach solution compared to the other tablets to neutralize, so I based my results on this observation. Introduction The purpose of doing this project was to figure out if antacid tablets work effectively since there are many tablets out there on the market. I predicted that the antacid tablets will neutralize the stomach solution I made and therefore be effective. I worked in the Breck School Science Lab under...
