What is the $pH$ of $0.1\,M\,N{H_3}$
A weak base $MOH$ of $0.1\,N$ concentration shows a $pH$ value of $9$ . What is the percentage degree of ionization of the base ? .......$\%$
A weak acid, $HA,$ has a $K_a$ of $1.00 \times 10^{-5}.$ If $0.100 \,mol$ of this acid is dissolved in one litreof water, the percentage of acid dissociated at equilibrium is closest to.....$\%$
The hydrogen ion concentration of a $0.006\,M$ benzoic acid solution is $({K_a} = 6 \times {10^{ - 5}})$
The degree of dissociation of $0.1\,M\,HCN$ solution is $0.01\%$ . Its ionisation constant would be
