1. What are the equilibrium concentrations of H3O+, CN-, and HCN in a 0.042 M solution of HCN? What is the pH of the solution?
Ka = 4.0 * 10^-10
[H3O+]-------------- M
[CN-]------------------- M
[HCN]----------------- M
pH----------------------
2. What is the pH of a 1.5 *10^-4 M solution of NaOH? What is the hydronium ion concentration of the solution?
Hydronium ion concentration --------------------M
