For e.g. Degree of ionization is inversely proportional to molar concentration. How does the degree of dissociation of a weak electrolyte vary with concentration of the solution . • The degree of dissociation `alpha` of a week electrolyte is where `n` is the number of ions given by `1 mol` of electrolyte. Try it now. Another way to prevent getting this page in the future is to use Privacy Pass. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. • Electrolyte when dissolved in water dissociate into their constituent ions. equation shows the relationship between an ion’s mobility and its molar conductivity. The degree of dissociation of weak electrolyte such as NH 4 OH, acetic acid can be determined by measuring the molar conductivity Λ, of the solution of the electrolyte at any given dilution.For e.g. Privacy (ostwald's law). So it increases with increasing dilution. Give λ° (H+) = 349.6 S cm2 mol–1 and λ° (HCOO– ) = 54.6 s cm2 mol–1.
