Question 122

Barium chloride solution reacts with sodium sulfate solution to form a precipitate of barium sulfate.

BaCl2(aq)+Na2SO4(aq)→BaSO4(s)+2NaCl(aq) \text{BaCl}_2(\text{aq}) + \text{Na}_2\text{SO}_4(\text{aq}) \rightarrow \text{BaSO}_4(\text{s}) + 2\text{NaCl}(\text{aq}) BaCl2​(aq)+Na2​SO4​(aq)→BaSO4​(s)+2NaCl(aq)

The theoretical yield of barium sulfate for this reaction was 7.25 g. The actual yield of barium sulfate obtained was 5.88 g.

Calculate the percentage yield of barium sulfate in this experiment. Give your answer to three significant figures.
