Weak Acids and Bases The citric acid in orange juice and the acetic acid in vinegar are weak acids. Toothpaste and shampoo contain weak bases. Weak acids and bases ionize or dissociate only slightly in water. Weak Acids A solution of acetic acid, CH 3COOH, and water can be described by the following equation. CH3 COOH H2OCH3 COO H3O+

the relative strength of acids and bases. The Lewis definition recognizes acid and bases in terms of their ability to accept or donate electron pairs. The strength of an acid or a base can be determined by the very nature of the reaction involved in a particular electron transfer process.

Strong acids and bases are 100% dissociated. Therefore we cannot interpret the relative acidic or basic strength among strong acids and bases. Strong acids and Strong bases have acidic and basic properties to an extreme. The situation is quite different for weak acids and bases. They dissociate partially and to different degrees.

Acids form hydrogen ions H + (H 2 O) n in aqueous solution. Bases form hydroxide ions in aqueous solution. Examples of Arrhenius acids (in water): HCl, H 2 SO 4, etc. Examples of Arrhenius bases (in water): NaOH, NH 3, etc. Arrhenius definitions only apply to aqueous solutions. A general Arrhenius acid-base reaction is the reaction between H ...
