1) Answer the following the questions regarding an acetic acid buffer solution.
a) A solution was prepared by dissolving 0.024 moles of acetic acid (HOAc; pKa =4.8 ) in water to give 1 liter of solution. What is the pH?
b)Then 0.009 moles of sodium hydroxide (NaOH) was added in to the solution. What is the pH of the solution? (In this problem, you may ignore changes in volume due to the addition of NaOH)
c)Additionally, 0.015 moles of NaOH is then added to the solution (2). What is the pH of the solution?
