Which one of the following salts,when dissolved in water,produces the solution with the highest pH? A)NaHCO₃ B)KClO₄ C)Na₂CO₃ D)CH₃NH₃Cl

Question

Quizplus · Accepted Answer

When NaHCO3 dissolves in water, it undergoes some hydrolysis to produce HCO3- and a small amount of OH-. However, Na2CO3 is a stronger base and will produce more OH- ions upon dissolution, resulting in a higher pH. Similarly, KCl is a neutral salt and will not significantly affect the pH of the solution. NH4Cl is an acidic salt and will actually lower the pH of the solution. Na2S is a basic salt and will produce OH- ions upon dissolution, but Na2CO3 is stronger and will produce more OH- ions, resulting in a higher pH.
