Question- Part 1) A 0.030 M solution was prepared by dissolving dipotassium cysteine, K2C, in water. Then 40.0mL of this solution was titrated with 0.060 M HClO4.
Calculate the pH at the first equivalence point.
Part 2) Calculate the quotient [C^2-]/[HC^-] in a solution of 0.050 M cysttainium bromide.
(amino acid cystein abbreviated as H2C)Answer for part 1 is 9.54 and part 2 is 7.9x10^-10
