Question

Error Analysis Questions for Metal Sulfate Hydrate Experiment (Part 2) A chemist doesn't dry the solid barium sulfate sufficiently to constant mass. As a result, would the experimental mass percentage of sulfate be overestimated, underestimated or remain unaffected? Explain your reasoning. A chemist doesn't add a sufficient quantity of barium chloride to reaction with and precipitate the sulfate ions. As a result would the experimental mass percentage of sulfate be overestimated, underestimated or remain unaffected? Explain your reasoning. A chemist forgets to add hydrochloric acid to the metal sulfate hydrate solution before the precipitation. Consequently, a portion of carbonate ions in solution from dissolved carbon dioxide also reacts and precipitates with barium ions. As a result, would the experimental mass percentage of sulfate be overestimated, underestimated or remain unaffected? Explain your reasoning.

Explanation / Answer

1. Overestimated as the water of hydration will be added in weight.

2. Underestimated as all the sulphate will not react. to form ppt

3. The barium carabonate will be added to total weight and will be overestimated.
