test for sodium benzoate, if it will be modified to a different harmful chemical substance in the stomach. In order to test the validity of this claim, a student will add sodium benzoate into an aqueous similar to the stomach acid, and that will be an aqueous of hydrochloric acid solution that have a PH range of 1-3, then the student will wait and observe if there is a newly formed substance or not. In order for the student to do this experiment correctly, a question should be asked regarding the experiment:

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

2. What are the normal ranges for the measurements listed in the blood and urine tests? The measurements taken will be through Arterial Blood Gas analysis which is used to diagnose the patient’s oxygenation levels, ventilation status, and acid-base balance. Normal PH blood levels are 7.35-7.45 which measures acidity or alkalinity. Normal Pco2 is 35-45 mmHg which measures carbon dioxide in the blood. Normal Bicarbonate is 22-26 mEq/L which acts as a buffer. Urinalysis PH levels range different from

Lab report Chemistry Title: Do different soda drinks have different amount of acid? What color they will change into? Goal: Nowadays we have a lot of varieties of soda drinks. The first soda drinks appeared in Western world in 17 century and it was just a mixture of lemon juicy, water and honey. So they were healthier than harmful. But the world has involved and manufactures began adding more preservatives. Nowadays are not many people aware that soda drinks

question we’re being asked is how can we neutralize acids and bases stop that the PH is 7. There are more than one variable that can told, but we’re going to say a few. One variable is the PH of the acid or base. If the acid is 1 and the base is 8, it’ll be harder to neutralize than something like 8 and 6. Another variable is the amount of acid and bases there are. If you have 20 ml of acid and 60 ml of base it’ll be harder to neutralize

Acids, Bases, PH Introduction. This experiment helped to understand difference between acid and base and there PH levels. We learned how to identify buffer. Buffer is substances that resist changes in PH when acid or base is added to solution. Also we learned that water is neutral. Its mean that water has an equal concentration of H and OH. PH number of water is 7. Acid’s PH numbers less than 7. Bases’ PH number

The Integumentary Morgan Davison Due: February 23, 2018 Period 4th -------------------------------- -------------------------------- Have you ever heard the phrase “I’m all skin and bones.” Well, that's not true. We have many parts in our body than skin and bones, and today I will be talking about the integumentary system. The integumentary system organs are the skin, the hairs, the nails, and the glands. Those organs don’t do everything in your body. But it does many thing to help

The Scientific Method with Lifesavers Lab Report Paul McPhee Lab1 Professor Stanley Aviron Performed September, 2013 Submitted September 2013 Introduction Candy is great and has been around for many years. I don’t know anyone that hasn’t tried candy of some sort at least once. There are a very many categories of candy but we will look at “ sweet, hard candy”, specifically the Lifesaver for this experiment. Food is chewed/dissolved or more simply, broken down into smaller
