Question

Derive an expression for ostwald dilution

Answer 1

Ostwald's dilution law is the application of the law of mass action to weak electrolytes in solution. Suppose an acid HA is dissolved in water, it will ionise as under: \underset{\underset{C(1- \alpha)} C}. Applying law of mass action,. K_a = \dfrac{[H^+][A^-]}. Where K_a is the dissociation (or ionisation) constant of the acid HA ...
