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.

Consider the reaction of Potassium Phosphate and Nickel (II) Bromide, where 15.00 ml of 0.7000M K3PO4 is mixed with 15.00ml of 0.2000M NiBr2 (and the final volume is 30.00 ml, that is there is no change in volume upon mixing). Your answer has to include all of the following: What is the limiting reagent? What is the identity and mass of precipitate formed? What is the concentration of the alkali metal that is a spectator ion? What is the concentration of the excess phosphate?
One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: Fe (s) + CuSO4 (aq) → Cu (s) + FeSO4 (aq)Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 200.mL copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass of 73.mg . Calculate the original concentration of copper(II) sulfate in the sample. Be sure your answer has the correct number of significant digits.

One method for chemical analysis involves finding a reactant that will precipitate the species of interest, but not the other species. The mass of the precipitate is then used to determine the mass of the species of interest present in the original sample. For example, calcium ions can be precipitated from an aqueous solution by adding of sodium oxalate Na2C2O4. The balanced equation is: Ca2+(aq) + Na2C2O4 (aq) --> CaC2O4 (s) + 2 Na+ (aq) Suppose you had a solution with approximately 15.0 g of calcium ions. Show by calculation whether the addition of 15.0 g of sodium oxalate will precipitate all of the calcium ions present in the sample.
