WebApr 28, 2024 · This is because a weak base (low Kb value) will generate a strong conjugate acid (high Ka value) (remember that K a K b =Kw for a conjugate acid-base pair). Examples for cations: Cation generated from a strong base: example Na + from NaOH NaOH (aq) → Na+(aq) + HO - (aq) strong base (high Kb) weak conjugate acid (low Ka) WebThe pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50. The lower the pKa of a Bronsted acid, the more easily it gives up its proton. The higher the pKa of a Bronsted acid, the more tightly the proton is held, and the less ...
