Which solution contains maximum number of ${H^ + }$ ion
$0.1\, M$ $HCl$
$0.1 \,M$ $N{H_4}Cl$
$0.1\, M$ $NaHC{O_3}$
$0.1 \,M$ $Na_2C{O_3}$
The degree of dissociation of $0.1\,M\,HCN$ solution is $0.01\%$ . Its ionisation constant would be
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
The solution of $N{a_2}C{O_3}$ has $pH$
The first and second dissociation constants of an acid $H_2A$ are $1.0 \times 10^{-5}$ and $5.0 \times 10^{-10}$ respectively. The overall dissociation constant of the acid will be
The $pH$ of a $0.1\ M$ aqueous solution of a very weak acid $(HA)$ is $3$. What is its degree of dissociation ?......$\%$
