WebVideo transcript. - [Voiceover] Let's look at how to use a pKa table. Remember from general chemistry that pKa is equal to the negative log of the Ka. And the lower the pKa value the stronger the acid. pka values are used a lot in organic chemistry, so it's really important to become familiar with them. WebJul 23, 2024 · Phosphoric acid (H 3 PO 4) has three ionization equilibria, as follows: H 3 PO 4 → H + + H 2 PO 4− (pKa 1 = 2.16), H 2 PO 4− → H + + HPO 42− (pKa 2 = 7.21) and HPO 42− → H + + PO 43− (pKa 3 = 12.32), phosphonic acid has two (pKa 1 = 1.3, pKa 2 = 6.70) and phosphinic acid one (pKa = 1.2), whereas e.g., sulphonic acid is dissociated in whole pH …

Phosphorous acid (or phosphonic acid (singular)) is the compound described by the formula H3PO3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds. Organic derivatives of phosphorous acid, compounds with the formula RPO3H2, are called phosphonic acids.
