Hello!

The compound that will form an acidic solution when dissolved in water is KHSO₄.

An acidic solution is one with a pH between 0-7. For it to be in this pH range, the solution needs to have hydronium ions (H₃O⁺). KHSO₄ generates these ions by the following dissociation reactions:

KHSO₄(s) →K⁺(aq) + HSO₄⁻ (aq)

HSO₄⁻(aq) + H₂O → H₃O⁺(aq) + SO₄⁻²(aq)

As the solution has hydronium ions, it will be an acidic solution. 

Ido not understand.
