WebFeb 2, 2024 · Weak bases react with water to produce the hydroxide ion, as shown in the following general equation, where B is the parent base and BH+ is its conjugate acid: …
Webup the same way as any other equilibrium expression. Many common weak acids are oxyacids, like phosphoric acid and nitrous acid. Other common weak acids are organic acids— those that contain a carboxyl group, the COOH group, like acetic acid and benzoic acid. For weak acid reactions: HA + H2O R H3O + + A− Ka = [H3O +][A−] < < 1 [HA] WebStrong acids dissociate fully in water to produce the maximum number of H+ ions. This means if you had one mole of hydrochloric acid (HCl) molecules, they would all ‘split’ to …
