A salt solution can be acidic, basic, or neutral. when dissolved in water, which of the following salts will not affect the pH: KCl, FeCl3, NaNO3, CaCO3, LiF, and NH4Br?

1 answer

Salts are made from acids and bases.
Those that are made from strong acids and strong bases will be neutral in water soln (have pH = 7 in water.)

Salts made from weak acids and strong bases will be basic in water soln.

Salts made from strong acids and weak bases will be acidic in water soln.

Salts made from weak acids and weak bases will be acid, basic, or neutral depending upon which is stronger; i.e., acid if Ka>Kb, basic if Kb>Ka, neutral if Ka=Kb.
