Bases:
Base,
in chemistry, any substance that in water solution is slippery
to the touch, tastes bitter, changes the colour of indicators (e.g., turns
red litmus paper blue), reacts with acids to form salts, and promotes
certain chemical reactions (base catalysis). Examples of bases are the
hydroxides of the alkali and alkaline earth metals
(sodium, calcium, etc.) and the water solutions of ammonia or
its organic derivatives (amines). Such substances
produce hydroxide ions (OH-) in water solutions
