For solution of weak electrolytic, the degree of ionization

A

Will be proportional to dilution

B

Will be proportional to concentration of electrolyte

C

Will be proportional to the square root of dilution

D

Will be reciprocal to the dilution

Text Solution

Verified by Experts

The correct Answer is:
C
Ostwald's dilution formula is `alpha^(2) = K(1- alpha)/C` but for weak electrolyte `alpha` is very small. So that `(1 - alpha)` is neglected for weak electrolytes. So for weak electrolyte the dilution formula is `alpha = sqrt((K)/(C))`.
