What is the pH of a 2.3 x 10-8 M solution of NaOH? You must consider the autodissociation of water at concentrations this low. Write the mass balance for sodium, charge balance, and the one equilibrium expression. This will give three equations and three unknowns (Na+, H+, and OH-). You can assume all activity coefficients are 1 at an ionic strength this low.
