Write the nature of the following salt solutions.
`NH_4Cl`

Explanation

Reaction of ions of the salt with water to form `H^(+) or OH^(-)` ions is called salt hydrolysis.
(a) `CH_(3)COONa` : Acetate ions react with water gives `OH^(-)` ions. Hence `CH_(3)COONa` aqueous solution is basic.
`CH_(3) COO^(-) + H_(2) O rarr CH_(3) COOH + OH^(-)`
(b) `NH_(4)Cl` : Aqueous solution of `NH_(4)Cl` is acidic. `NH_(4)^(+)` ions react with water to give `H_(3)O^(+)` ions.
`NH_(4)^(+) + H_(2)O rarr NH_(3) + H_(3)O^(+)`
(c) NaCl : Batch `Na^(+) and Cl^(-)` do not react. Hence aqueous solution of NaCl is neutral.
