  1. A \(CH_3COONa\)
  2. B \(Na_2SO_4\)
  3. C \(CuSO_4\)
  4. D \(Na_2CO_3\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(CuSO_4\)

Step-by-step Solution

Detailed explanation

A salt of strong acid and weak base forms aqueous solution having \(\mathrm{pH}\) less than 7 (that is, it forms an acidic solution). \(\mathrm{CuSO}_4\) is salt of strong acid \(\mathrm{H}_2 \mathrm{SO}_4\) and weak base \(\mathrm{Cu}(\mathrm{OH})_2\).
