Given the two concentrations of $HCN$ $(K_a = 10^{-9})$ are $0.1 \ M$ and $0.001 \ M$ respectively. What will be the ratio of their degrees of dissociation?

The ionisation constant of a weak acid $(HA)$ in terms of molar conductivity at infinite dilution $(\Lambda _m^\infty)$ and molar conductivity at concentration $C$ $(\Lambda _m)$ is given by:

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

What is the relationship between the degree of dissociation of a weak base and its concentration?

Which of the following will not conduct electricity in aqueous solution?

It has been observed that gaseous hydrogen chloride is a very poor conductor of electricity,but a solution of hydrogen chloride gas in water is a good conductor of electricity. This is due to the fact that:
