Question
Which process involves the movement of electrons from reductant to oxidant ?
- Double replacement
- Neutralization
- Redox reaction
- Sublimation
Hint:
Oxidation is lose of electron and reduction is gain of electron.
The correct answer is: Redox reaction
Redox reactions are oxidation-reduction chemical reactions in which the reactants undergo a change in their oxidation states. The term ‘redox’ is a short form of reduction-oxidation. A redox reaction involves the transfer of electrons from one species to another. In a redox reaction, the oxidation state of two species changes, with one being reduced and the other one being oxidized.
Oxidation is lose of electron and reduction is gain of electron. Oxidant is reduced and reductant is oxidized. Redox reaction involves the movement of electrons from reductant to oxidant.
