Calculate the equilibrium constant, Ka for the acid, HA if, at equilibrium, the pH of a 1.85 M solution of HA is 3.13? I know that: Use pH = -log [H+] first and solve for [H+]. Then use Ka = [H+][A-]/[HA] to solve for Ka. [A-] = [H+] [HA] is given in the problem. I keep getting it wrong, any ideas??
