For which salt should the aqueous solubility be most sensitive to pH? A)MgCl₂ B)Mg(NO₃)₂ C)MgF₂ D)MgBr₂ E)MgI₂

Question

Quizplus · Accepted Answer

The aqueous solubility of MgF2 is highly sensitive to pH changes because it undergoes hydrolysis reactions with water, which results in the formation of insoluble Mg(OH)2. As pH increases, the concentration of hydroxide ions also increases, leading to increased formation of Mg(OH)2 and decreased solubility of MgF2. In contrast, the other salts listed do not undergo significant hydrolysis reactions with water and thus their solubility is not as strongly affected by changes in pH.
