Consider the following statements :
- 1Potassium carbonate is a salt of a weak acid and a weak base.
- 2Ammonium nitrate is a salt of a strong acid and a weak base.
- 3Ammonium acetate is a salt of a weak acid and a weak base.
Which of the statements given above are correct?
general-sciencechemistry
- A1 and 3 only
- B2 and 3 only
- C1 and 2 only
- D1, 2 and 3
Explanation
Potassium carbonate is a salt of a weak acid (carbonic acid) and a strong base (KOH), so statement 1 (weak acid and weak base) is incorrect. Ammonium nitrate is a salt of a strong acid (nitric acid) and a weak base (ammonia), so statement 2 is correct. Ammonium acetate is a salt of a weak acid (acetic acid) and a weak base (ammonia), so statement 3 is correct. Hence 2 and 3 only are correct.
