$HCN$ is $1 \%$ ionized in its $0.2 \ M$ aqueous solution. At the same temperature,what would be its percent ionization in its $0.02 \ M$ aqueous solution?

Calculate the percentage dissociation of a $0.05 \ M$ solution of a weak electrolyte if its molar conductivity and molar conductivity at infinite dilution are respectively $3.3 \ \Omega^{-1} \ cm^2 \ mol^{-1}$ and $132 \ \Omega^{-1} \ cm^2 \ mol^{-1}$. (in $\%$)

Which of the following substances,when dissolved in water,will give a solution that does not conduct electricity?

The degree of dissociation of $0.1 \ N$ $CH_3COOH$ is (given $K_a = 1 \times 10^{-5}$) approximately $......$

If $\alpha$ is the degree of ionization,$C$ is the concentration of a weak electrolyte,and $K_a$ is the acid ionization constant,then the correct relationship between $\alpha$,$C$,and $K_a$ is:

$A$ weak monobasic acid is $1\%$ ionised in $0.1 \ M$ solution at $25 \ ^{\circ}C$. The $\%$ ionisation in its $0.025 \ M$ solution is
