MCQ
$NH_4CN$ is a salt of weak acid $HCN (K_a = 6.2 \times 10^{-10})$ and a weak base $NH_4OH (K_b = 1.8 \times 10^{-5})$. A one molar solution of $NH_4CN$ will be:
- Aneutral
- Bstrongly acidic
- Cstrongly basic
- ✓weakly basic
$ = 7 - \frac{{4.74}}{2} + \frac{{9.20}}{2}$
$ = 7 - 2.37 + 4.6$
$ = 9.23{\text{ weakly basic}}$
