Document Summary

The procedure for this experiment can be found on pages 48-50 in general chemistry. Carbon copies of the data table have been attached to the back of this lab report. 0. 0974g x 100 = 88. 3% actual mass of caco3. All 15 net ionic equations have been attached to the back of this lab report. The sample of chalk was used to find the mass and percent yield of caco3. The list of net ionic equations are attached to the back of this report. The unknown number was one and the identity of the unknown was found to be cacl2. The mass of caco3 was found to be. The theoretical yield of caco3 was found to be 0. 0974g. The percent yield of caco3 was found to be 88. 3%. Possible sources of error for this lab included the fact that according to the solubility rules, some of the reactions should not have formed a participate when they did.
