Acid –Base Reactions

Acid –Base Reactions
An acid has been
defined as a substance which when dissolve in water ionizes to produce hydrogen
ion (H+) as the only positive ion while a base is a substance that neutralizes an acid or a substance that
dissolves in water to produces hydroxide ion (OH) as the only negative ion.  
Perfectly, acid is been used and seen
daily without much debate, for a given chemical substance to be called an acid,
it must have sour taste and extremely corrosive in nature due to the presence
of hydrogen ions.  There
are three widespread definitions for acids: the Arrhenius definition, the Bronsted-Lowry
definition, and the Lewis
definition. The Arrhenius definition defines acids as a chemical substances
which increase the concentration of hydrogen ions (H+), or additional
hydronium ions (H3O+), when
dissolved in aqueous solution. Simply speaking, the Bronsted-Lowry definition is an extension:
an acid is a  chemical substance which
can behave as a proton donor. Thus, any compound which can easily be deprotonated can be considered an acid. Examples
include alkanols and amines which contain O-H or N-H wreckage. A Lewis acid is
a substance that can accept a pair of
electrons to form a covalent bond. Examples of Lewis acids
include all metal cations, and
electron-deficient molecules such as boron
trifluoride and aluminium trichloride.
examples of acids include Nitric and hydrochloric
acid (a solution of hydrogen chloride which is found in gastric acid in the stomach which works by
activating digestive enzymes), acetic
acid (vinegar is a dilute
solution of this liquid), sulfuric
acid(used in car batteries), and tartaric acid (a solid used in baking). As these
examples show, acids can be solutions or pure substances, and can be derived
from solids, liquids, or gases. Strong acids and some concentrated weak acids are corrosive, but there are exceptions such as carboranes and boric
This topic takes a convincing look at the quantitative
reaction between and acid and a base  and
the analysis of the reaction between this two using volumetric analysis,
relevant calculations to assist in effective understanding will also be
