Question

If degree of ionization $\left(\alpha \right)$ of a weak electrolyte $AB$ is very less, then $\alpha$ is

• A. directly proportional to the square root of volume of solution
• B. inversely proportional to the dilution
• C. inversely proportional to the square root of concentration
• D. directly proportional to concentration

Answer 1

Answer: (A), (C)

The correct options are
A directly proportional to the square root of volume of solution
C inversely proportional to the square root of concentration

$\alpha =\sqrt{\frac{K}{C}}=\sqrt{\frac{K\times V}{n}}$

So directly proportional to the square root of the volume of solution and inversely proportional to the square root of concentration.
