Question

Quizplus · Accepted Answer

According to the common-ion effect, the solubility of a salt is decreased in a solution containing a common ion. In this case, the common ion is Br-. PbBr₂ will be least soluble in a solution where the concentration of Br- ions is the highest. Among the given options, option C contains the highest concentration of Br- ions because CaBr₂ is a strong electrolyte and dissociates completely in water to give Ca2+ and 2Br- ions. Therefore, PbBr₂ is expected to be the least soluble in option C.
