Aqueous solution of `NH_(4)Cl` is acidic. Explain.

Explanation

`to` Given salt NH CI is obtained by the reaction of strong acid (HCI) and weak base `(NH_(3)OH)`
`to` The ionisation of `NH_(4)Cl` as follows
`NH_(4)^(+) +Cl^(-) hArr NH_(4)Cl`
`to` The above salt under goes cationic hydrolysis
`NH_(4)^(+)H_(2)O hArr NH_(4)+H^(+)`
`:.` The equation solution of salt is acidic due to greater H+ ion concentration than OH ion concentration.
`:. P_(H) lt 7`
