A is more concentrated than B; B is more concentrated than R; Topic: Coordination Compounds . WebThe pure un-ionised acid has the structure: The hydrogens aren't released as ions until you add water to the acid, and even then not many are released because phosphorous acid is only a weak acid. Phosphorous acid has a pK a of 2.00 which makes it stronger than common organic acids like ethanoic acid (pK a = 4.76).
