In which of the following solutions would solid PbBr₂ be expected to be the least soluble at 25°C? A)0)1 M H Br B)0)1 M NaBr C)0)1 M CaBr₂ D)0)1 M KNO₃

Question

Quizplus · Accepted Answer

PbBr₂ is least soluble in solutions with high concentrations of divalent cations such as Ca2+. This is due to the formation of insoluble calcium salts with Pb2+ ions, resulting in the precipitation of PbBr₂. Therefore, option C, which contains 0.1 M CaBr₂, would be expected to result in the least soluble PbBr₂.
