AlCl 3+3 H 2 O leftharpoons underset text Weak base Al ( OH )3+ underset text Strong acid 3 HCl Aqueous solution of AlCl 3 is a solution of strong acid ( HCl ) and weak base ( Al ( OH )3). Thus, the resultant solution will be acidic.

Q. Aqueous solution of $A lC l_{3}$ is:

acidic

basic

amphoteric

none of these

$A lC l_{3} + 3 H_{2} O ⇌ Weak base A l (O H)_{3} + Strong acid 3 H Cl$
Aqueous solution of $A lC l_{3}$ is a solution of strong acid $(H Cl)$ and weak base $(A l (O H)_{3})$ . Thus, the resultant solution will be acidic.
