Experiment 1: How Dense is an Egg Lab
1. According to my calculations and observations, the fresh egg was denser then the
stale egg. The fresh egg had an average density among all the trials of about 1.06
Group E Experiment #1
Final Report: Heat Changes Involved in Neutralizing Acids and Bases
Introduction: The purpose of the lab is to determine the heat changes associated with
neutralizing acids and bases. A pharmaceutical manufacturing pla
1. The Copper chloride was the limiting reagent in the experiment. With stoichiometry, it
can be proven that in the reaction between zinc and copper chloride to produce zinc
chloride and copper, copper chloride is the limiting reagent. Also I could tell t
1. My team and I decided to divide the standards among each of us equally. Each group
member had the responsibility of determining the physical observations, the solubility,
the density, and the acidity/basicity of 2g of each of the two assigned standards
1. Observe and record the physical appearance of the unknown compound.
2. Determine if the compound is soluble by placing a "spatula-tip" amount of the
unknown compound in a test tube. (about 0.010g)
3. Add 10 dro

Experiment 5: Studying Chemical Reactions
Procedure Part A
1. All of the ionic solutions are in the dropper bottles. Place 5 drops of the first ionic
solution in a small test tube.
2. Add 5 drops of the second ionic
Preparing the "original" iron solution
1. Get a vitamin tablet and grind it with a mortar and pestle.
2. Using a 150 mL beaker, measure out 25 mL of a 6M HCl and place the ground
vitamin tablet in the solution.
3. Swirl the beaker and wait for e
1. Use a buret to fill it up exactly 25.0 mL of copper chloride solution into a 250 mL
beaker (known as the reaction beaker).
2. If you put more or less then 25.0 mL use this same volume as well as the date on the
reagent bottle in order to cal

Open Ended Project Procedure: Heat Changes Involved in Neutralizing Acids & Bases
First the HCl was titrated in order to calculate its exact molarity.
25 ml of 1 M HCl solution
1. Make 250 mL of carbon dioxide free water by boiling it on a hot plate for 5 minutes
then allow it to cool in the beaker with a watch glass over it.
2. Clean your buret with a brush using soap and water and then rinse it with distilled
1. In the first group of four reactions, Iron phosphate and calcium phosphate are the two
products that are insoluble in water. In the three of the four reactions a cloudy white or
yellow formed. This indicated the formation of a precipitate, caused by th
I used the strategy of briefly summarizing what my main points were as well as
restating my thesis so that the reader could easily see the full picture of how my
thesis and main points connect. I also slightly touched upon what I began writing
