Cyanic acid (HOCN) is a weak acid with K a = 3.5 10 4 . Consider

Question:

Cyanic acid (HOCN) is a weak acid with K_a = 3.5 × 10^–4. Consider the titration of 25.0 mL of 0.125 M HOCN with 0.125 M NaOH. Calculate the pH of the solution at each of the following points.

(a) Before any NaOH has been added.

(b) After 12.5 mL of NaOH has been added.

(d) After 27.0 mL of KOH have been added.

(e) Use your calculator or a spreadsheet to plot the titration curve, and use your graph to estimate the pH at the equivalence point.
