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
Correct Answer: C
Solution :
Ostwald?s dilution formula is \[{{\alpha }^{2}}= K(1 - \alpha )/C\] for weak electrolyte a is very small. So that \[(1 - \alpha )\] is neglected for weak electrolytes. So for weak electrolyte the dilution formula is\[\alpha =\sqrt{\frac{K}{C}}\].
