Which of the following solution will be acidic

Options

  1. A0.1 M CH ₃ COONa ⁻
  2. B0.1 M FeSO ₄
  3. C0.1 M K ₂ SO ₄ Al ₂ ( SO ₄ )₃ 24 H ₂ O
  4. D0.1 M ( NH ₄ )₂ SO ₄

Correct answer

D. 0.1 M ( NH ₄ )₂ SO ₄

Step-by-step solution

In case of B, C and D, the salt are of weak base and strong acid which undergo hydrolysis to give acidic solutions CH ₃ COONa however, on hydrolysis gives basic solution.
