Base

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+

base

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/

Base

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...

base

Historically, base is a substance that yields an OH - ion when it dissociates in solution, resulting in a pH>7. In the Brønsted definition, a base is a substance capable of accepting a proton in any type of reaction. The more general definition, due to G.N. Lewis, classifies any chemical species capable of donating an electron pair as a base. Typi...
