This experiment will create a reaction of sodium carbonate andcalcium chloride dihydrate to
produce a precipitate of calcium carbonate. This formula is:

Na2CO3(aq) + CaCl2. 2H2O(aq) ? CaCO3(s) + 2NaCl(aq) + 2H2O

1. Put on your goggles.

2. Weigh out 1.0 g of CaCl2·2H2O and put it into the 100-mL beaker.Add 25 mL of distilled
water and stir to form the calcium chloride solution. Use onlydistilled water since tap
water may have impurities that interfere with the experiment.

3. Use stoichiometry to determine how much Na2CO3 you will need fora full reaction.
