From the following which reaction is not redox reaction ?

Answer»

`2H_(2)+O_(2)to2H_(2)O`
`Cu^(++)ZntoZn^(++)+Cu`
`HCl+H_(2)OtoH_(3)O^(+)+Cl^(-)`
`Cl_(2)+2H_(2)O+SO_(2)to4H^(+)+SO_(4)^(-2)+2CL^(-)`

Solution :In this reaction there is only REDUCTION of `H_(2)O_(2)` hence it is not a redox reaction.
