Chapter 10, Problem 10-30(choose chapter or problem)
This problem deals with the amino acid cysteine, which we will abbreviate H2C. (a) A 0.030 0 M solution was prepared by dissolving dipotassium cysteine, K2C, in water. Then 40.0 mL of this solution were titrated with 0.060 0 M HClO4. Calculate the pH at the first equivalence point. (b) Calculate the quotient [C2]/[HC] in a solution of 0.050 0 M cysteinium bromide (the salt H3CBr).
