Question

Quizplus · Accepted Answer

The addition of sulfuric acid (HSO4-) will react with bismuth sulfide (Bi2S3) to form bismuth hydroxide (Bi(OH)3) and sulfur dioxide gas (SO2). The sulfur dioxide gas will react with any remaining water to form sulfuric acid. Therefore, the overall reaction is 2Bi2S3(s) + 9H2SO4(l) + 3H2O(l) → 6Bi(OH)3(s) + 9H2S(g) + 9H2SO4(l). However, since only 3 moles of sulfuric acid are present in the reaction, only half of the bismuth sulfide will react, resulting in the formation of Bi(OH)3. Therefore, the correct answer is C, 2Bi(OH)3 + 3H2SO4 → Bi2(SO4)3 + 6H2O.
