Ostwald&rsquo;s dilution formula is (α )2=K(.1-α .)/C but for weak electrolyte α is very small. So that (.1-α .) is neglected for weak electrolytes. So for weak electrolyte the dilution formula is α =√(K/C) .

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

Will be reciprocal to the dilution

Will be proportional to dilution

Will be proportional to the square root of dilution

Will be proportional to concentration of electrolyte

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

Ostwald’s dilution formula is (α)2=K(1−α)/C but for weak electrolyte α is very small. So that (1−α) is neglected for weak electrolytes. So for weak electrolyte the dilution formula is α=CK​​ .
