At $25\,^oC$, the dissociation constant of $CH_3COOH$ and $NH_4OH$ in aqueous solution are almost the same. The $pH$ of a solution $0.01\, N\, CH_3COOH$ is $4.0$ at $25\,^oC$. The $pH$ of $0.01\, N\, NH_4OH$ solution at the same temperature would be
$3$
$4$
$10$
$10.5$
The hydrogen ion concentration in weak acid of dissociation constant ${K_a}$ and concentration $c$ is nearly equal to
Heat of neutralisation of weak acid and strong base is less than the heat of neutralisation of strong acid and strong base due to
Discuss the factors affecting acid strength by examples.
The $pH$ of two equimolar weak acids are $3.0$ and $5.0$ respectively. Their relative strength is
A $0.1\,N $ solution of an acid at room temperature has a degree of ionisation $ 0.1$ . The concentration of $O{H^ - }$ would be
