Project 3 Identification and Synthesis of an Unknown Ionic Compound Mitchell Morgan CEM-161-007 Josh Ward 28th October 2015 Abstract The chief objective of this experiment was to identify the unknown compound. The following tests were conducted to eventually establish the identity of the compounded: qualitative solubility tests, anion and cation tests, flame test, and the formation of a precipitate. The physical properties of the unknown ionic compound found that it has no smell and was…

Observations: This experiment was divided into two parts: one part was to observe the properties of a single Alka Seltzer tablet and the second part was to find the percentage of CO2. In the first part of the experiment, the visible properties of Alka Seltzer were observed and recorded. Each Alka Seltzer contains the same three ingredients: 325 mg of Aspirin, 1000 mg of Citric Acid, and 1916 mg of Sodium Bicarbonate. Two of Alka Seltzer’s ingredients, Citric Acid and Sodium Bicarbonate (Baking…

Introduction: The purpose of this lab was to use the general chemical knowledge to identify 10 different unknown solutions. There are two main techniques that were used which are, measuring their pH, and, reacting all of the solutions together. Identifying an unknown solution is an essential skill for anyone who is going to work in a lab because many times, the label might not be accurate, or damaged. Procedure: Safety Precautions: Eye protection - Avoid skin contact. Procedure: Ten…

In the biomolecule lab, we conducted the lipid chromatography experiment to separate a mixture of biomolecules from lipids. If a positive test is conducted by the end of the experiment, there should be smudges aligned vertically on the chromatography paper, or silica gel strip, indicating the separation of different lipid molecules that were present in the substance. In contrast, if a negative test is conducted there would be no smudges aligned vertically on the chromatography paper. Substances…

Introduction: The purpose of the experiment was to determine the density of powdered grape. The company Gatorade has advertised that G2 powder replenishes fluids and electrolytes in the body’s blood stream during exercise. G2 has aided in staying hydrated, “maintain normal muscle performance, heart rate and brain activity” (1). In relation, there has been a rise in sports drink purchase to improve athletic performance. The experiment examined a basic level of G2 powders composition, the…

The purpose of this lab is to calculate the chemical formula of a hydrate compound made up of copper, chlorine, and water molecules by using the law of definite proportions. The water of hydration of the copper chloride hydrate sample will be determined as well as the mass of copper and chlorine through a chemical reaction. The results will be used to calculate the moles of copper and chlorine and then the empirical formula of the compound. Techniques used: In this experiment, different…

The extraction lab began with a .517g mixture of benzoic acid, p-nitroaniline, and azobenzene charged in a 125 mL Erlenmeyer flask mixed with 50 mL of Et2O. Once dissolved, the mixture is transferred the mixture into separatory funnel and begin acid extraction. 15 mL of 3 M HCl is added to the separatory funnel and inverted until a phase boundary is present. An additional 15 mL of 3 M HCl was then added and inverted again. The aqueous layer was removed through the separatory funnel and placed…

To begin the first part of the experiment, zeolite and magnetized zeolite had to be synthesized. First, it was necessary to set up a contraption to hold a thermometer in place. This was done using a split cork and a 3 prong clam on a ring stand. 50 mL of 3.0 M NaOH was then added to a 250 mL beaker with a magnetic stir bar placed inside. After placing the solution on the stir bar, 3.7560 g of (sodium aluminate) was added to the solution. The thermometer was also added to the solution, but it…

PH levels are a measure of how acidic or basic your beverage is. They show what beverages are more acidic, like soda, and what beverages are more basic, like water. It’s measured on a scale from one to fourteen. One through six are the acid levels, seven is the only neutral level, and eight through fourteen are the basic levels. First, get 2 drinks of choice and pour them into two different cups. Then, record its pH level, as well as the room temperature. Next, take another liquid and mix it…

If a quantitative solution needs to be prepared, there are a series of steps that must be followed in order to get accurate answers. there are several objects needed to prepare it, including a 500 ml graduated cylinder, deionized water, and sodium phosphate dodecahydrate as the aqueous solution. The first step is to find the mass of the solution, sodium phosphate. In the formula, sodium's atomic mass is multiplied by 3 because there is the original weight times 3 atoms of sodium in the formula.…
