7.43 The ionization constant of HF, HCOOH, and HCN at 298K are 6.8 × 10–4
1.8 × 10
–4 and 4.8 × 10–9 respectively. Calculate the ionization constants of the corresponding conjugate base.

NEET SOLUTION:

It is known that,

${\mathrm{K}}_{\mathrm{b}}=\frac{{\mathrm{K}}_{\mathrm{w}}}{{\mathrm{K}}_{\mathrm{a}}}$
