Study Notes
Classification of Acids and Bases
- Ranking the strength of acids and bases depends on the definition of acid and base used.
Arrhenius Acids and Bases
- Arrhenius defined an acid as a substance that gives H+ and a base as one that gives OH- in 1884.
- Acids produce hydrogen ions, H+(aq), in aqueous solutions according to Arrhenius.
- Bases produce hydroxide ions, OH-(aq), when dissolved in water according to Arrhenius.
- Phosphoric acid, H3PO4, is an example of a triprotic acid.
Strong Acids
- Strong acids ionize completely when in solution.
- Salts are formed (as well as water) when acids and bases react.
- Strong acids can be used to prepare salts.
Preparation of Salts
- Salts can be prepared by reacting acids and bases.
