If degree of ionisation is $0.01$ of decimolar solution of weak acid $HA$ then $pKa$ of acid is
The hydrogen ion concentration of a $0.006\,M$ benzoic acid solution is $({K_a} = 6 \times {10^{ - 5}})$
Heat of neutralisation of weak acid and strong base is less than the heat of neutralisation of strong acid and strong base due to
Dissociation constat of weak acid $HA$ is $1.8 \times {10^{ - 4}}$ calculate Dissociation constant of its conjugate base ${A^ - }$
Find $pH$ of $5 \times 10^{-3}\, M$ $H_2CO_3$ solution having $10\%$ dissociation
