A student determines that an aqueous solution that contains 0.302 M sodium fluoride and 0.103 M hydrofluoric acid, also has a H3O+ concentration of 2.95×10-4 M. Based on these data, calculate the value of the equilibrium constant K for the equilibrium:
HF(aq) + H2O H3O+(aq) + F-(aq)
(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
