Question

Which of the following concentrations has the largest degree of dissociation for a weak acid?

• A. 1.0 M
• B. 0.5 M
• C. 0.10 M
• D. 0.01 M

Answer 1

The correct option is D 0.01 M

The degree of dissociatoin increases with dilution by Ostwald's Law i.e.,
$\alpha =\sqrt{\frac{K}{c}}$
$\alpha \propto \frac{1}{c}$
