Bronsted - Lowry Concept of Acid and Bases
In 1923, a Danish Chemist J.H Bronsted and an English chemist T.M Lowry independently proposed new definitions for acids and bases. They proposed that: An acid is a substance that can donate a proton. A base is a substance that c..

In 1923, J.N.Bronsted and T.M.Lowry proposed a more general theory known as the Bronsted-Lowry proton transfer theory. According to this concept, any hydrogen containing species (a molecule, a cation or an anion), which is capable of donating one or more protons ..
Bronsted-Lowry Acid
A substance which can donate a proton is a Bronsted-Lowry acid..
Relative Strength of Bronsted Acids and Bases
According to Bronsted-Lowry theory, an acid is a proton donor and base is a proton acceptor. Therefore the strength of an acid or a base is determined by its tendency to lose or gain protons. A strong acid is a substance which loses a pro..

Lewis Concept of Acids and Bases
Although Bronsted-Lowry theory was more general than Arrhenius' theory of acids and bases, it failed to explain the acid-base reactions which do not involve transfer of proton. For e.g., it fails to explain how acidic oxide such as anhydrous CO 2 , ..
Relative Strengths of Conjugate Acid-Base Pairs
A stronger Bronsted acid will have a higher tendency for donating a proton to the base, hence would tend to exist as its conjugate base. The conjugate base so formed will have very little tendency to pick up a proton, hence would act as a weak ..
On the Acidity of Bases
The acidity of a base is equal to the number of hydroxyl ions it has. It is also the number of hydrogen ions with which a base can combine as one hydrogen ion combines with one hydroxyl i..
Mechanism of Buffer Action
The buffering action of buffer solutions can be explained in terms of the Bronsted-Lowry concept of acids and bases as follow..
