what is meant by oxidant and reductant
Answers
Answer:
Oxidant = it is a substance that has the ability to oxidize other substances , to cause them to lose electrons. examples are oxygen, hydrogen peroxide and the halogens.
Reductant= it is an element (such as calcium) or compound that loses (or donates) an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons, it is said to have been oxidized.
In redox processes, the reductant transfers electrons to the oxidant. Thus, in the reaction, the reductant or reducing agent loses electrons and is oxidized, and the oxidant or oxidizing agent gains electrons and is reduced.
OR
The species which donates electrons is reductant.
The one which accepts electrons oxidant.
Oxidation: removal of electrons
Reduction: addition of electrons
The one which is undergoing oxidation is called reductant.
The one which is undergoing reduction is called oxidant.

FOR EXAMPLE..
The reaction between magnesium metal and oxygen, for example, involves the oxidation of magnesium.
2 Mg(s) + O2(g) ------> 2 MgO(s)
