If degree of ionisation is $0.01$ of decimolar solution of weak acid $HA$ then $pKa$ of acid is
A weak monoprotic acid of $0.1\, M,$ ionizes to $1\% $ in solution. What will be the $pH $ of solution
Given the two concentration of $HCN (K_a = 10^{-9})$ are $0.1\,M$ and $0.001\,M$ respectively. What will be the ratio of degree of dissociation ?
A weak acid is $ 0.1\% $ ionised in $0.1\, M $ solution. Its $pH$ is
${K_a} = 1.4 \times {10^{ - 5}}$ of propanoic acid. Calculate its $pH$ of $0.1$ $M$ solution.
