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)

$\alpha=\sqrt{\frac{K_{a}}{C}}$

Answer 2

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
