Question

The aqueous solution of AlCl3 is acidic due to the hydrolysis of (A) aluminium ion (B) chloride ion (C) both aluminium and chloride ions (D) none of the above

Tardigrade Admin · Accepted Answer

The aqueous solution of AlCl 3 is acidic due to the hydrolysis of aluminium ion. Al 3++6 H 2 O arrow[ Al ( H 2 O )6]3++3 Cl - Al ( OH 2)63++ H 2 O arrow[ Al ( H 2 O )5( OH )]2++ H 3 O + alt hydrolysis Cl - does not hydrolyse.

Q. The aqueous solution of $A lC l_{3}$ is acidic due to the hydrolysis of

aluminium ion

chloride ion

both aluminium and chloride ions

none of the above

The aqueous solution of $A lC l_{3}$ is acidic due to the hydrolysis of aluminium
ion.
$A l^{3 +} + 6 H_{2} O \to [A l (H_{2} O)_{6}]^{3 +} + 3 C l^{-}$
$A l (O H_{2})_{6}^{3 +} + H_{2} O \to [A l (H_{2} O)_{5} (O H)]^{2 +} + H_{3} O^{+}$
alt hydrolysis
$C l^{-}$ does not hydrolyse.
