Equimolar solutions of the following substances were prepared separately. Which one of these will record the highest pH value?

1. BaCl₂
2. AlCl₃
3. LiCl
4. BeCl₂

Correct answer: LiCl

Solution

LiCl is a neutral salt formed from a strong acid (HCl) and a strong base (LiOH), so its solution will have the highest pH (close to 7). The other salts hydrolyze to some extent, lowering the pH.
