Which oxychloride has maximum $pH$
$NaClO$
$NaCl{O_2}$
$NaCl{O_3}$
$NaCl{O_4}$
(a) Maximum $pH \,HClO$ is a weak acid all of these. So that the salt of weak acid is also weak.
The hydrogen ion concentration in weak acid of dissociation constant ${K_a}$ and concentration $c$ is nearly equal to
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
Degree of dissociation of $0.1\,N\,\,C{H_3}COOH$ is (Dissociation constant $ = 1 \times {10^{ – 5}}$)
The dissociation constants of two acids $HA_1$ and $HA_2$ are $3.0 \times 10^{-4}$ and $1.8 \times 10^{-5}$ respectively. The relative strengths of the acids will be
The $pH$ of $ 0.1 \,M$ solution of a weak monoprotic acid $1\%$ ionized is
