How can Kohlrausch's law of independent migration can be applied for calculating the degree of dissociation `(alpha)` of weak electrolytes ?

Explanation

The `wedge_(m)^(oo)` values can also be used to calculate the degree of dissociation `(alpha_(c ))` and also the dissociation constants of weak acids and weak bases. According to Arrhenius :
`alpha_(c )=(wedge_(m)^( c))/(wedge_(m)^(oo))`
where `wedge_(m)^( c)` as is the molar conductivity of the electrolyte at concentration c and `alpha_(c )` is its degree of dissociation at concentration c.
Knowing the degree of dissociation, `alpha`, the dissociation constant `K_(c )` of a weak electrolyte can be calculated by using the relation:
`K_(c )=(c alpha^(2))/((1-alpha))`
