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. WebIf you think about what that does for your KA, that's gonna give you an extremely high value for your KA. All right, so KA is much, much, much greater than one here. That's how we … ind 4622car insuranceWebFor a weak acid or base, the equilibrium constant for the ionization reaction quantifies the relative amounts of each species.
