Question

The relationship between ionization and change in concentration of any weak electrolyte is represented as:

• A. $\alpha=\frac{K_{a}}{C}$
• B. $\alpha=\sqrt{\frac{K_{a}}{C}}$
• C. $\alpha=K_{a} \cdot C$
• D. $\alpha=\frac{\sqrt{K_{a}}}{C^{2}}$

Answer 1

Answer: (B)

The relationship between ionisation and change in concentration of any weak electrolyte is represented by $\alpha=\sqrt{\frac{K a}{C}}$
where $\alpha=$ degree of dissociation
$C=$ molar concentration
$K_{a}=$ ionisation constant
