The correct answer to the above question is (a), which is CH₃COOK.

  • Turmeric solution gives reddish-brown colour in basic medium.
  • From (a) we get, potassium acetate (CH3COOK)  salt of a strong base and weak acid
  • From (b) we get, copper sulphate (CuSO₄)  salt of strong acid and weak base
  • From (c) we get, sodium sulphate (Na₂SO₄)  - salt of strong acid and strong base
  • From (d) we get, Ferric chloride (FeCl₃ )-the salt of a weak base and strong acid

All the other compounds are weak bases in aqueous aolution. Only potassium acetate is a salt of a strong base and weak base. So turmeric solution will turn red by an aqueous solution of potassium acetate.
