Solution: A 0.010 M solution of the weak acid HA has an osmotic pressure (see chapter on solutions and colloids) of 0.293 atm at 25°C. A 0.010 M solution of the weak acid HB has an osmotic pressure of 0.345 atm

Problem

A 0.010 M solution of the weak acid HA has an osmotic pressure (see chapter on solutions and colloids) of 0.293 atm at 25°C. A 0.010 M solution of the weak acid HB has an osmotic pressure of 0.345 atm under the same conditions.

HA [HA(aq) ⇌ A(aq) + H+(aq)] or HB [HB(aq) ⇌ H+(aq) + B(aq)] ?

What are the equilibrium constants for the ionization of these acids?
