1. Review the following reaction, where sodium carbonate and calcium chloride
dihydrate react in an aqueous solution to create calcium carbonate (solid precipitate
formed in the reaction), a salt (sodium chloride), and water.
Na2CO3(aq) + CaCl2
.2H2O(aq) → CaCO3(s) + 2NaCl(aq) + 2H2O(l)
2. Put on your safety gloves and goggles.
3. Use the graduated cylinder to measure 25 mL of distilled water. Add 25 mL of distilled
water to each of the two 100 mL glass beakers.
