Question

A salt X is dissolved in water having pH =7. The resulting solution has a pH more than 7. The salt is made by neutralisation of (A) A strong acid and strong base (B) A strong acid and weak base (C) A weak acid and weak base (D) A weak acid and strong base

pH > 7 implies the solution is basic. Since salt on hydrolysis in water gives basic solution. Therefore, it is a salt of weak acid strong base and undergoes anionic hydrolysis in aqueous solution A- +HOH leftharpoons HA+OH-

Q. A salt $X$ is dissolved in water having $p H = 7$ . The resulting solution has a pH more than $7$ . The salt is made by neutralisation of

A strong acid and strong base

A strong acid and weak base

A weak acid and weak base

A weak acid and strong base

$p H > 7$ implies the solution is basic. Since salt on hydrolysis in water gives basic solution. Therefore, it is a salt of weak acid strong base and undergoes anionic hydrolysis in aqueous solution
$A^{-} + H O H ⇌ H A + O H^{-}$
