Chemistry concepts
BasesThere are certain base properties which were noted early in the history of chemistry. According to the Arrhenius acid-base concept, a substance is classified as a base if it ionizes to form hydroxide ions OH(-) in aqueous solution. Other systems classify substances as bases if they act as proton receptors (Bronsted-Lowry theory) or as electron-pair donors (Lewis theory). These two classification methods are not limited to solutions in water.

Base StrengthA base which ionizes almost completely in solution is said to be a strong base, wheras one which has a small degree of ionization is a weak base. Of the common bases, sodium hydroxide is a strong base. Sodium bicarbonate is a weak base. The basicity of solutions is measured in terms of the pH of the solution, and strong bases will raise the pH more for a given molarity of solution. |
