Q. For solution of weak electrolytic , the degree of ionization

NTA AbhyasNTA Abhyas 2022

Solution:

Ostwald’s dilution formula is $\left(\alpha \right)^{2}=K\left(\right.1-\alpha \left.\right)/C$ but for weak electrolyte $\alpha $ is very small. So that $\left(\right.1-\alpha \left.\right)$ is neglected for weak electrolytes. So for weak electrolyte the dilution formula is $\alpha =\sqrt{\frac{K}{C}}$ .
