Question
A student determines that an aqueous solution that contains 9.32×10-2 M sodium cyanide and 0.163 M hydrocyanic acid, also has a H3O+ concentration of 8.05×10-10 M. Based on these data, calculate the value of the equilibrium constant K for the equilibrium:
(1) as is usually done, without the inclusion of water in the expression for K: K =
(2) for comparison, with the inclusion of water in the expression for K: K =
