MCQ
In weak electrolytic solution, degree of ionization
- AWill be proportional to dilution
- BWill be proportional to concentration of electrolyte
- ✓Will be proportional to the square root of dilution
- DWill be reciprocal to the dilution
✓
Answer
Correct option: C.
Will be proportional to the square root of dilution
(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 {\frac{K}{C}} $.
