Question:

Hydrogen cyanide gas (HCN) is a powerful respiratory inhibitor that is highly toxic. It is a very weak acid (K_a = 6.2 × 10^–¹⁰) when dissolved in water. If a 50.0-mL sample of 0.100 M HCN is titrated with 0.100 M NaOH, calculate the pH of the solution at the following points.

a. After 8.00 mL of 0.100 M NaOH has been added

b. At the halfway point in the titration

c. At the equivalence point
