A solution of hydrocyanic acid is prepared by dissolving 0.10 mol HCN in enough water to make 1.0 L of solution. If 0.0050 mol of NaCN is added to the solution with no increase in volume, what is the concentration of H+ when equilibrium is re-established? Use concentrations to get equilibrium constant. CN ions added and used Na+ as a spectator ion.
