Read the statement and study the reaction.
NaCN dissociates into Na+ and CN– ions in water (H2O).
CN– hydrolyzes water according to following reaction:
CN– + H2O ⇌ HCN + OH–
A sample solution has 0.051 M of CN– ions, and the pH of the solution is 10.96. What is the equilibrium constant for this reaction?
9.7 × 10–6
6.22 × 10–6
1.63 × 10–5
3.10 × 10–5
