WebAnd we know that the equilibrium, the equilibrium favors the acid with the higher pKa value, favors the formation of the acid with the higher pKa value. And it's a little bit tricky cause we have two negative values for our pKa. But negative two is closer to zero than negative three, so negative two is the higher pKa.
