Question

Aqeous solution of salt of weak acid and strong base

Moderate

A

Has [H⁺] < [OH^-]
B

Is basic in nature
C

Has pH greater than 7
D

All the above

Solution

$eg ., {CH}_{3} COONa + H_{2} O \to {CH}_{3} COOH + \underset{Strong Base}{{Na}^{+} {OH}^{-}}$
Hence aq. solution of weak acid with strong base is basic in nature.
Aqueous solution of a salt of weak acid and strong base is basic in nature as given by the formula
$\large {P^H} = \frac{1}{2}\left[ {{P^{{K_w}}} + {P^{{K_a}}} + \log C} \right]$
OR
P^H > 7
