WHAT IS MEANT BY REDOX REATION/.
A chemical reaction involving oxidation of one substance and the reduction of the other is called  a redox reaction .Redox reaction involves loss or gain of electrons where oxidation and reduction occur simultaneously 
For example , Cl2   +    H2S    _________>   2HCl    +S  
Hydrogen sulphide (H2S) is oxidised to sulphur (S)   (removal of hydrogen by chlorine )
Chlorine (Cl2) is reduced to hydrogen chloride (HCl)   (gains  hydrogen from hydrogen sulphide  )
In the above reactions hydrogen sulphide is a reducing agent and chlorine is the oxidising agent .
