In which of the following solutions would solid PbCl₂ be expected to be the least soluble at 25°C? A)0)1 M HCl B)0)1 M NaCl C)0)1 M CaCl₂ D)0)1 M KNO₃

Question

Quizplus · Accepted Answer

According to the common-ion effect, the presence of additional chloride ions from the salt will reduce the solubility of PbCl₂. Thus, the solution with the highest concentration of chloride ions, which is 0.1 M CaCl₂, would cause the least amount of PbCl₂ to dissolve.
