lewis acids and bases

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 ..

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 pair of ele..

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..

A substance which can accept a pair of electrons is termed Lewis acid..

A substance which can donate a pair of electrons is called Lewis base..

Accordingly, carboxylic acids evolve hydrogen with electropositive metals as alcohols do. Carboxylic acids react with weaker bases such as carbonates and bicarbonates to evolve CO 2..

Acid Base Titrations - In acid base titrations, a base is added to an acid successively (or vice versa) and the pH of the solution is noted after every addition. The plot of pH against the amount of base (or acid) added..
