Lewis Concept of Acids and Bases
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..
Lewis Concept of Acids and Bases
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 ..

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 , SO 2 , SO ..
Lewis Acid - Base Reaction
Whenever a Lewis acid reacts with a Lewis base, a covalent bond is formed. For example, CO 2 (Lewis acid) reacts with OH - (Lewis base) to give HCO 3 - (bicarbonate ion), BF 3 (boron trifluoride) behaves as a ..

Acid Base Equilibrium-Arrhenius Concept of Acids and Bases - Based on certain characteristic observable properties, electrolytes were classified into acids and bases..
Arrhenius Concept of Acids and Bases
Arrhenius in 1887 put forward this concept. Accordingly, an acid is a hydrogen-containing compound, which gives free hydrogen ions when dissolved in water. A base is a hydroxyl group containing compound which gives free hydroxyl ions (OH - ) when dissolved in water. T..

A base is a hydroxyl group containing compound which gives free hydroxyl ions (OH - ) when dissolved in water. T..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 hydrogen ion, it is in fact giving away a proton. Thus, the ..

A substance which can accept a pair of electrons is termed Lewis acid..
Bronsted - Lowry Concept of Acids 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 containing species (a molecule, a cation or an anion),..
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 can accept a proton. These defi..

Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
