bronsted lowry concept of acid and bases

Bronsted - Lowry Concept of Acids and Bases - 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 cont..

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 can accept ..

A substance which can donate a proton is a Bronsted-Lowry acid..

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 fail..

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..

Acid Base Equilibrium-Arrhenius Concept of Acids and Bases - Based on certain characteristic observable properties, electrolytes were classified into acids and bases..

Modern Concept of Acid and Base - When acids combine with bases, acids give hydrogen ions to the base, and the base accepts them. We have already seen that a hydrogen ion is a proton. So when acid gives away a..

In 1938 G.N. Lewis put forward a more generalized acid-base concept. According to this concept, an acid is a species (charged or uncharged), which can accept a pair of electrons and a base is a species (charged and uncharged), which can donate a pai..

When acids combine with bases, acids give hydrogen ions to the base, and the base accepts them. We have already seen that a hydrogen ion is a proton. So when acid gives away a hydrogen ion, it is in fact giving away a proton. Thus, t..

An acid is a substance which can furnish hydrogen ions in its solution. Examples: ..
