Provide the following information for a titration analysis involving a titrant and titrand, where the titrand is a weak, diprotic acid (Ka1 = 1.00 x 10-4; Ka2 = 1.00 x 10-8; Vol=0.01000 L; FH2A=0.1000 M) and the titrant is a strong monoprotic base that has been standardized (0.1000 M KOH). Calculate the pH at the following volumes of added strong base: A. 0.00 mL of strong base (KOH) added, B. at one-half the equivalence volume, C. at the first equivalence volume, D. at 3/2 the first equivalence volume, E. at the second equivalence volume (2*Ve1), and F. at 0.03000 L of added hydroxide. Sketch the titration curve, making sure to include ALL pertinent information.
