Which salt from following forms aqueous solution having pH less than 7 ?

Options

ACH₃COONa
BNa₂SO₄
CCuSO₄
DNa₂CO₃

Correct answer

C. CuSO₄

Step-by-step solution

A salt of strong acid and weak base forms aqueous solution having pH less than 7 (that is, it forms an acidic solution). CuSO ₄ is salt of strong acid H ₂ SO ₄ and weak base Cu ( OH )₂ .
