Objective: To determine relative molecular mass of a soluble base‚ X2 CO3 by carrying out an acid-base titration with the following reaction ‚ knowing the amount of hydrochloric acid used and the amount of substance Z used. Hypothesis: The X in substance Z is a group 1 element because substance Z is a soluble metal carbonate and would most likely be sodium or potassium because these elements are commonly used. Materials 100 cm3 beaker‚ 250 cm3 beaker‚ 250 cm3 volumetric flask with stopper

How Much Water Does Epsom salts Contain? Purpose The purpose of the experiment was to find the percent of water in Epsom salts by heating it. To find the percent of water in a hydrate‚ the hydrate must be heated. The experiment did not only show how dehydration occurs‚ but this experiment also gives an accurate and definite portrayal of the amount of water that is removed Background Information A hydrate is any compound that contains water. An anhydrous compound is a hydrate in which the water

What is the Identity of this Hydrate? Date Performed: May 30‚ 12 Date Submitted: June 6‚ 2012 Name: 2968 Instructor: Reid A hydrate was given to our group and the identity of the hydrate was unknown. The lab workers were told to determine the identity of the unknown hydrate. The identity of the hydrate could be determined by calculating the hydrate’s percent of water. So the lab workers set out to determine the water percent of the unknown hydrate. The percent of any compound or element
