If the pH is 2 units below the pKa, the HH equation becomes, -2 = log A/HA, or .01 = A/HA. This means that the functional group will be about 99% protonated (with either 0 or +1 charge, depending of the functional group).

WebApr 6, 2024 · This is due to the acidic nature of Cr3+ (aq). This is a complex with 6 water ligands surrounding the central metal ion. Because the Cr3+ ion is small and highly charged this has the effect of removing electron density from the 0-H bonds, making them weaker. If a base is present then H+ ions will be lost: [Cr(H2O)6]3+ +H2O ⇌ [Cr(H2O)5OH]2+ +H3O+.

The first reaction is the dissociation of sulfuric acid. The equation is: H 2SO4(aq) +H 2O(l) → H 3O+(aq) +H SO− 4 (aq) This creates a hydrogen sulfate anion and hydronium cations. Then, the hydrogen sulfate anion dissociates further into sulfate ions and even more hydronium ions.
