A student determines that an aqueous solution that contains 0.262 M potassium cyanide and 0.218 M hydrocyanic acid, also has an H3O+ concentration of 4.06×10-10 M. Based on these data, calculate the value of the equilibrium constant K for the equilibrium:
HCN(aq) + H2O H3O+(aq) + CN-(aq)
Calculate K as is usually done, omitting the solvent, water, from the expression for K: K
