(a) 0.1000 L of ultrapure water (ionic strength µ=0, you can assume the ionization of protons, hydroxide, and weak acid contribute negligibly to µ). (b) 0.1000 L of 0.03333 M Na2SO4 salt solution. Use the concentration definition of pH for both solutions (pH=-log[H+ ]) but where appropriate correct for ionic strength effects. The Debye-Hückel equation parameter, α, is equal to 0.9, 0.35, 0.6 for H+,OH–, A– respectively.
