Degree of dissociation is $10\%$ for $10^{-3}\, M$ solution of $H_2CO_3$ then $pH$ of solution is

Which oxychloride has maximum $pH$

For a weak acid $HA,$ Ostwald's dilution law is represented by the equation

The dissociation constant of an acid $HA$  is $1 \times {10^{ - 5}}$. The $pH$ of $0.1$ molar solution of the acid will be

The $pH$ of $ 0.1 \,M$  solution of a weak monoprotic acid  $1\%$  ionized is

The hydrogen ion concentration in weak acid of dissociation constant ${K_a}$ and concentration $c$ is nearly equal to
