What happens in redox reactions?

Electrons are transferred between substances

In redox reactions, if one substance gains an electron, what about another substance?

The substance loses an electron

In redox reactions, if one substance loses an electron, what about another substance?

The substance gains an electron

Oxidation

1. Loses electrons

2. To combine with oxygen

3. Bonds are increased with oxygen

Reduction

1. Gains electrons

2. Formation of metal from compounds

Oxidizing agents

1. Accepts its gain of electrons

2. Goes through REDUCTION

3. (not to be confused with actual oxidation)

Reducing agents

1. Donates electrons

2. Goes through oxidation

3. (not to be confused with actual reduction)
