Aqueous solution of AlCl ₃ is acidic towards litmus while of NaCl is not. The correct reason behind this is
Options
- AAlCl ₃ furnishes OH ⁻ ion in the solution
- BAlCl ₃ furnishes H ⁺ ion in the solution
- CAlCl ₃ furnishes both H ⁺ well as OH ⁻ ion in the solution
- DAlCl ₃ is the salt of strong base and strong acid
Correct answer
B. AlCl ₃ furnishes H ⁺ ion in the solution
Step-by-step solution
AlCl ₃ is the salt of weak base and strong acid which renders H ⁺ ions on hydrolysis. Thus, aqueous solution of AlCl ₃ is acidic in nature. Al ³⁺+3 H ₂ O Al ( OH )₃+3 H ⁺ On the other hand, NaCl is the salt of strong acid and strong base which does not undergo hydrolysis.
