A substance that reacts with acid to produce a salt and water only. It does this by accepting a hydrogen ion from the acid. An example is ammonia which accepts a proton to become the ammonium ion - NH4+
a substance capable of reacting with an acid to form a salt. A typical base is sodium hydroxide (caustic), with the chemical formula MOH. For example, sodium hydroxide combines with hydrochloric acid to form sodium chloride (a salt) and water/

A Base is a substance whose ions or molecules can accept H+
ions. The Bronsted-Lowry definition of a base is that it is a 'proton acceptor'. By strength of a base is meant the tendency with which it will accept H+
ions; the stronger the base the more readily it will accept H+
ions. The terms 'strength' and 'concentr...Found on http://www.encyclo.co.uk/local/20138
