Your task is to prepare a buffer solution of 1.00 L of 0.250 M acetic acid and solid sodium hydroxide. Start by writing the equation for the reaction that will form the buffer (hint: you must have both acetic acid and acetate ion in the solution; where will the acetate ion come from? Neglecting the volume change on addition of NaOH (MM 40.0 g/mol), what mass is required to produce a buffer of pH 3.75? What pH will the buffer show after the addition of 250.0 mg of solid KOH (MM 56.1 g/mol) ? Assume no volume change on addition of the base. The Ka for acetic acid is 1.8 X 10^-5.
