WebFor example, the Ka constant for acetic acid (CH 3 COOH) is 0.0000158 (= 10 -4.8 ), but the pKa constant is 4.8, which is a simpler expression. In addition, the smaller the pKa value, the stronger the acid. For example, the pKa value of lactic acid is about 3.8, so that means lactic acid is a stronger acid than acetic acid. prototype alex mercer weaponsWebThese values indicate that the products of a strong acid reaction are heavily favored compared to the reactants. So very large numbers for Ka and negative values for pKa for strong acids.
