MCQ
The aqueous solution of $AlC{l_3}$ is acidic due to the hydrolysis of
- AAluminium ion
- BChloride ion
- CBoth aluminium and chloride ion
- ✓None of these
✓
Answer
Correct option: D.
None of these
d
$AlCl _3$ is a Salt of $SA$ and $W B$ i.e
$AlCl _3$ is a Salt of $SA$ and $W B$ i.e
$Al ( OH )_3+ HCl \rightleftharpoons AlCl _3+ H _2 O$
when we make aquous solution of $AlCl_3$ this undergo cationic hydrolysis, And form hydrated ion complex due to which solution becomes acidic.
$Al ^{3+}+ H _2 O \longrightarrow\left[ Al \left( H _2 O \right)_6\right]^{3+}$
