(b) A buffer solution is prepared by adding 0.10 liter of 2.0 molar acetic acid solution to 0.1 liter of a 1.0 molar
sodium hydroxide solution. Compute the hydrogen ion concentration of the buffer solution.
(c) Suppose that 0.10 liter of 0.50 molar hydrochloric acid is added to 0.040 liter of the buffer prepared in (b).
Compute the hydrogen ion concentration of the resulting solution.
