The
dibasic compound B (pKb1 5 4.00, pKb2 5 8.00) was titrated with
1.00 M HCl. The initial solution of B was 0.100 M and had a volume
of 100.0 mL. Find the pH at the following volumes of acid added and
make a graph of pH versus Va: Va 5 0, 1, 5, 9, 10, 11, 15, 19, 20,
and 22 mL.

A 100.0-mL aliquot of 0.100 M diprotic acid H2A (PK1 = 4.00, PKa2 = 8.00) was titrated with 1.00 M NaOH. Find the pH at the following volumes of base added. a) 1 ml, b) 11 mL, c) 20 mL and d) 22 mL.
A 100 mL volume of a 0.100 M weak base (pKb = 5.00) was titrated with 1.00 M HClO4. Find the pH at the following volumes of added acid: 0.00, 1.00, 5.00, 10.00, and 10.10 mL.
A 100.0 mL aliquot of 0.100 M monoprotic acid H2A (pK1 = 4.00) was titrated with 1.00 M NaOH. Find the pH at the following volumes of base added: Vb = 0, 5, 9, 10 and 11 mL. Sketch the titration curve.
3) Consider the dibasic compound "B". This compound has a pKo 4.00 and a pK,2 8.00 (a) Sketch a crude titration curve if a flask of 100.00 mL of a 0.1000 M B solution is titrated against 1.000 M HCl. (since you already worked through #2 above you should easily be able to add approximate numbers to each axis.) (b) Indicate the equation you would use to calculate pH in each of the major zones of the graph. I expect...
