A weak acid HA (pKa = 5.00) was titrated with 1.00 M KOH. The acid solution had a volume of 100.0 mL and a molarity of 0.100 M. Find the pH at the following volumes of base added and make a graph of pH versus Vb: Vb = 0, 1, 5, 9, 9.9, 10, 10.1, and 12 mL. Step by step please. will rate 5 stars even if you don't complete the graph..just show me how to do the pH part. Answers are (3.00, 4.05, 5.00, 5.95, 7.00, 8.98, 10.96, 12.25).
