A base dissolves to make an alkali. Added: Statement: "All alkali are bases but not all bases are alkali" Alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Alkalis are best known for being bases that dissolve in water. (The most common form is hydroxide.) This broad use of the term is the probability that it is occurred due to the alkalis were the first bases known to obey the Arrhenius definition of a base and are still among the most common bases. From brã nsted-Lowry acid-base theory, the term alkali in chemistry is normally restricted to those salts containing alkali and alkaline-earth metal elements. A base is most commonly thought of as an aqueous substance that can accept H+ ions. A soluble base is also often referred to as an alkali if hydroxide ions (OH − ) are involved. This refers to the brã nsted-Lowry theory of acids and bases. Alternative definitions of bases include electron pair donors (Lewis), and as sources of hydroxide anions (Arrhenius). Examples of simple bases are sodium hydroxide (NaOH, which is therefore an alkali and the base) and ammonia (NH 3 that is not "alkali", but the base).
