When a 1.000 g sample of CuSO 4 • 5 H 2 O(s) was heated so that the waters of hydration were driven off, the mass of the anhydrous salt remaining was found to be 0.6390 g. What is the experimental value of the percent water of hydration? CuSO 4 • 5 H 2 O(s) + HEAT ----> CuSO 4 (s) + 5 H 2 O (g) 1.000 g 0.6390 g
Pre-Lab Work Pre-lab work is to be completed and turned in on the day the lab is performed. 1. Title The title should be descriptive. For example, “pH Titration Lab” is a descriptive title and “Experiment 5” is not a descriptive title. 2. Date This is the date the student performed the experiment. 3. Purpose

Experiment 5: Percent Water in a Hydrated Solution Abstract: The purpose of this experiment was to determine the percent by mass of water in a hydrated salt. A hydrated salt is a salt that has water molecules chemically bound to it. An anhydrous hydrated salt is a salt in which fire can easily remove the water molecules from the salt. Using the gravimetric analysis method, the sample salt was ...

Jun 13, 2011 · The chemical reaction of anhydrous calcium chloride with water is . CaCl (s) + H 2 O (l) --> CaCl.nH 2 O (s) Anhydrous Hydrated . calcium chloride drying agent . The presence of tertiary alkyl halides can be tested by using silver nitrate test. Some of the product formed in the experiment is added with silver nitrate solution.
Experiment 5 –Percent Water in a Hydrated Salt. Pre-Lab Hints. 1. Note definition of deliquescent in the introduction. 2. See side notes for part A, as well as part 1 of Technique 15C in the front portion of your lab manual. 3. Mass of water in sample is the mass lost by heating (initial minus final). Water % is 100 times the g of water divided by the initial g of hydrate sample.
