Which of the following aqueous salt solutions is acidic?
Options
- ASodium chloride
- BAmmonium nitrate
- CPotassium cyanide
- 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:
