Determine the pH increase of a solution after 0.10 mol of NaOH is added to 1.00 L of a solution containing 0.15 M HC2H3O2 and 0.20 M NaC2H3O2. If this same amount of NaOH was added to 1.00 L of pure water then what would be the pH increase of the resulting solution? Compare these two values. pH increase in buffer: ? pH increase in pure water: ?
