3. An aqueous solution of calcium bromide reacts with an aqueous solution of potassium phosphate to produce a precipitate.
a) Write the balanced chemical equation that represents the precipitation reaction.
b) Suppose you have 52.56 mL of a 0.125 mol / L aqueous solution of calcium bromide. Which
volume of a 0.236 mol / L potassium phosphate solution you need to add to ensure that all
does the calcium bromide present in the solution react in terms of stoichiometric proportion?
