Which of the following aqueous solutions of salts is neutral?
Options
- ANH ₄ NO ₃
- BKCN
- CKNO ₃
- DCuCl ₂
Correct answer
C. KNO ₃
Step-by-step solution
NH ₄ NO ₃ is a salt of a weak base ( NH ₄ OH ) and a strong acid ( HNO ₃ ). Its aqueous solution is acidic. KCN is a salt of a strong base ( KOH ) and a weak acid ( HCN ). Its aqueous solution is basic. KNO ₃ is a salt of a strong base ( KOH ) and a strong acid ( HNO ₃ ). Its aqueous solution is neutral. CuCl ₂ is a salt of a weak base ( Cu(OH) ₂ ) and a strong acid ( HCl ). Its aqueous solution is acidic. Answer: KNO ₃
