Which of the following aqueous salt solutions is acidic?

Options

  1. ASodium chloride
  2. BAmmonium nitrate
  3. CPotassium cyanide
  4. DSodium carbonate

Correct answer

B. Ammonium nitrate

Step-by-step solution

Sodium chloride is a salt of a strong acid ( HCl ) and a strong base ( NaOH ), so its aqueous solution is neutral. Ammonium nitrate is a salt of a strong acid ( HNO ₃ ) and a weak base ( NH ₄ OH ), so its aqueous solution is acidic due to the cationic hydrolysis of the ammonium ion. Potassium cyanide is a salt of a weak acid ( HCN ) and a strong base ( KOH ), so its aqueous solution is basic. Sodium carbonate is a salt of a weak acid ( H ₂ CO ₃ ) and a strong base ( NaOH ), so its aqueous solution is basic. Answer:
