it should be option A. H
[ because H gained oxygen ( O ) ]
Oxidation is defined by :
- the loss of electrons
- the loss of hydrogen ( H )
- the gain of oxygen ( O )
- increase in oxidation state
Reduction is defined by :
- the gain of electrons
- the gain of hydrogen ( H )
- the loss of oxygen ( O )
- decrease in oxidation state
(Basically, oxidation n reduction is opposite of each other)
