Acid-Base Reaction

Lewis Definition :
       Acid - base reaction is a chemical reaction. In this reaction acids are electron pair acceptors (lewis acid ). Bases are electron pair donars ( Lewis base ).

General Formula :

A⁺   +   B^-    →   A-B

Example :

BF₃   +   F^-   →   BF4^-

HCl   +   OH^-  →   H2O  +  Cl^-

H⁺    +   OH^- →   H2O

H⁺    +  NH3  →   NH4⁺

COCl⁺  +  Cl^-  →   COCl2
