Problem- 1 a 0030 m solution was prepared by dissolving, Ask an Expert

Academics

Problem- 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.

2) Calculate the quotient [C^2-]/[HC^-] in a solution of 0.050 M cysttainium bromide.

(amino acid cystein abbreviated as H2C)

Answer for A is 9.54 and B is 7.9x10^-10

I want to know how this is done please show all steps in detail.
