Gravimetric Analysis of Calcium Carbonate and Hard Water Introduction In this laboratory activity, you will develop calculating skills and facility with the techniques of gravimetric analysis. In particular, we will practice quantitative transfer and vacuum filtration. You will perform a precipitation reaction that involves preparing and combining solutions of sodium carbonate, Na2CO3, and calcium chloride, CaCl2. The balanced chemical equation for this reaction predicts the amount of precipitate that will be formed. Careful isolation, drying and weighing of the precipitate will confirm the calculations and the percent yield. Pre-Lab Questions 1. Define the term gravimetric analysis. Describe the procedure used in this activity, and identify two other common examples of gravimetric analysis.
