Question

A solution containing 50.0 mL of 0.050 M acetic
acid (CH3COOH, a weak acid with a Ka equal to 1.75 × 10-5) istitrated with 0.100 M NaOH.
(a) Write the net ionic reaction for the reaction that occursduring the titration before the
equivalence point is reached.
(b) What is the numerical value of the equilibrium constant for thetitration reaction?
(c) Calculate the pH of the solution before the titrationbegins.
(d) Calculate the pH at a point 25% of the way to the equivalencepoint.
(e) Calculate the pH at the equivalence point.
(f) Calculate the pH at 25 mL past the equivalence point.
(g) Draw a rough sketch of the titration curve that you havegenerated, and mark the curve with
the letters a-d to represent the points at which you havecalculated the pH
