5.) Write a complete, balanced chemical equation for when solutions of calcium chloride and
sodium sulfate are allowed to react according to the following equation. Balance the equation
and work the problems that follow.
Na So. (aq)
CaCl, (aq) →
NaCl(aq)
CaSO. (5)
b.) The above reaction is completed by allowing 45.0 ml of 0.250 M sodium sulfate to react
with 25.0 ml of 0.450 M calcium chloride. The percent yield for this reaction is reported
to be 92.7 %. Calculate the experimental mass of the precipitate that can be expected to be
recovered from this reaction. 1.42 g
