Heat of neutralisation of weak acid and strong base is less than the heat of neutralisation of strong acid and strong base due to
Energy has to be spent for the total dissociation of weak acid
Salt of weak acid and strong base is not stable
Incomplete dissociation of weak acid
Incomplete neutralisation of weak acid
Ionisation constant of $CH_3COOH$ is $1.7 \times 10^{-5}$ and concentration of $H^+$ ions is $3.4 \times 10^{-4}$. Then find out initial concentration of $CH_3COOH$ Molecules
The ionization constant of benzoic acid is $6.5 \times {10^{ - 5}}$ at $298$ $K$ temperature. Calculate $pH$ of its $0.15$ $M$ solution.
For a weak acid $HA,$ Ostwald's dilution law is represented by the equation
If the dissociation constant of an acid $HA$ is $1 \times {10^{ - 5}},$ the $pH$ of a $ 0.1$ molar solution of the acid will be approximately
If degree of ionisation is $0.01$ of decimolar solution of weak acid $HA$ then $pKa$ of acid is
