oxidizer – מילון אנגלי-אנגלי
oxidizer (Amer.)
n.
oxidant, oxidizing agent, agent or substance causing oxidization, substance that oxidizes another substance (also oxidiser)
Oxidizing agent
In chemistry,
oxidizing agent has two meanings. In one sense, an oxidizing agent is a chemical species that removes an
electron from another
species. It is one component in an
oxidation-reduction (redox) reaction. In the second sense, an oxidizing agent or an oxidizer is a chemical species that transfers electronegative atoms, usually oxygen, to a substrate. Combustion, many explosives, and
organic redox reactions involve atom-transfer reactions.
oxidizer
Noun
1. a substance that oxidizes another substance
(synonym) oxidant, oxidiser, oxidizing agent
(hypernym) chemical agent
(derivation) oxidize, oxidise, oxidate
Oxidizer
(n.)
An agent employed in oxidation, or which facilitates or brings about combination with oxygen; as, nitric acid, chlorine, bromine, etc., are strong oxidizers.

About
oxidizing agent (oxidant; oxidizer)
Compare with
reducing agent .An oxidizing agent is a substance that
oxidizes another substance by removing electrons from it. Oxidizing agents cause other substances to be oxidized in chemical reactions while they themselves are reduced. For example, nitrate ion is an oxidizing agent in the following reaction:
Cu(s) + 4 H
+(aq) + 2 NO
3-(aq) Cu
2+(aq) + 2 H
2O(
) + 2 NO
2(g)
Copper gets oxidized (its oxidation number goes from 0 to +2) while the nitrogen gets reduced (from +5 in nitrate to +4 in nitrogen dioxide).
