WebbAnswer (1 of 2): As acids go, this is a very weak acid which makes the problem easier as you will see. Remember, that pH = -log [H+] so we have to determine the [H+]. Also, pKa = -log Ka (so Ka = 4.9 * 10^-10) and, for the equilibrium HCN = H+ + CN- Ka = [H+][CN-]/[HCN] So, let [H+] = x, ther...
