Problem
A chemist combines 50.0 mL of 0.250 M calcium chloride solution with 40.0 mL of 0.300 M ammonium phosphate solution at 25 °C. The reaction produces an insoluble solid and one soluble product.
The chemist subsequently filters, washes, and dries the solid product.
(a) Write the balanced molecular equation for the reaction, including phase labels.
(b) Write the complete ionic equation for the reaction.
(c) Derive the balanced net ionic equation.
(d) Identify the spectator ions present in the original reaction mixture and state their concentrations after the reaction has gone to completion. Assume additive volumes and 100 % yield of the solid product.
(e) Calculate the maximum mass, in grams, of the precipitate that can be collected under the stated conditions.
