Question
During an oxidation - reduction reaction, the number of electrons gained is
- Equal to the number of electrons lost
- Equal to the number of protons gained
- Less than the number of electrons lost
- Less than the number of protons gained
Hint:
Oxidation is the loss of electron and reduction is gain of electron, redox is a balanced reaction.
The correct answer is: Equal to the number of electrons lost
Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases. Redox reaction is oxidation-reduction reaction, one part is oxidized and the other is reduced.
During an oxidation - reduction reaction, the number of electrons gained is equal to the number of electrons lost.
