Which one of the following salts,when dissolved in water,produces the solution with the lowest pH? A)NaCl B)KCl C)MgCl₂ D)AlCl₃

Question

Quizplus · Accepted Answer

Aluminum chloride (AlCl3) dissociates in water to form aluminum cations (Al3+) and chloride anions (Cl-). The presence of the aluminum cations in solution can effectively hydrolyze water, leading to the formation of hydronium ions (H3O+), giving the solution an acidic pH. Therefore, AlCl3 produces the lowest pH solution among the given options.
