Austin Neely August 31st, 2015 Experiment #01 The Determination of the Percent of Water in a Compound CHEM 1315‐ 025 Purpose of the Experiment & Techniques: The purpose of this experiment is to determine the percent of water in a hygroscopic compound. This will be done by boiling off the water only leaving the other element of the hygroscopic compound. When water molecules bond with the structure of solid substances this creates an ionic compound. By heating the compound, it is possible

Enzymes are biological catalysts or assistants that consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. They can either launch a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia

tissue so that the desired element is still stained. The eosin step is a counterstain step that is used mostly in the routine staining. The pH range plays important part in causing eosin bind to the section. If pH is below 4, eosin is converted to free acid which bind to the sections, resulting the muddy section appear.

reflexes, cerebral edema, confusion, seizures and coma. Sodium is important is regulating the back and forth of the water in the body and brain. Chloride is higher than normal, normal being 96-106 mml/L. Chloride is responsible for the fluid and acid-base balance in the body. Symptoms of high serum chloride or hyperchloremia are dehydration, high blood sugar, dyspnea, intense thirst, weakness and coma. CO2 is low, normal CO2 levels are 23-29 mmol/L. Low CO2 levels can be caused by hyperventilation

The basic aqueous layer separated previously was then transferred into a 250 mL beaker, and a 50 mL of HCl was collected in a 100 mL beaker. Using a pipette, HCl was slowly added to the basic aqueous substance to acidify it. The lab TA stated that the solution would turn cloudy once acidified, but this did not happen, despite more than 50 drops being added. When the pH was tested, it showed that the pH was definitely 1, despite the solution not being cloudy. The volume of the NaOH and HCl mixture

substances such as red cabbage and turmeric can be used to determine the acidity or basicity of other substance. The household substances that were used are Vinegar, Detergent, Bicarbonate Soda, Lemon Juice and Ammonia. Lemon juice and Vinegar are acids and have the pH value of 2.3 and 2.9 respectively. Detergent, bicarbonate soda and ammonia are all alkaline and have the pH value of 10.9, 8.4 and 11.9 respectively (Smith, 2009). Based on the experiment conducted and results tabulated, by using red
