What is the approximate value of the equilibrium constant, K_n, for the neutralization of nitrous acid with ammonia, shown in the equation below? The K_a for HNO_2 is 4.5 times 10^-4 and the K_b for NH_3 is 1.8 times 10^-5. HNO_2(aq) + NH_3(aq) NH_4NO_2(aq) What is the hydronium ion concentration in a solution prepared by mixing 50.00 mL of 0.10 M HCN with 50.00 mL of 0.050 M NaCN? Assume that the volumes of the solutions are additive and that K_a = 4.9 times 10^-10 for HCN. What is the pH of a solution prepared by mixing 25.00 mL of 0.10 M CH_3CO_2H with 25.00 mL of 0.050 M CH_3CO_2Na? Assume that the volume of the solutions are additive and that K_a = 1.8 times 10^-5 for CH_3CO_2H.
