What is a reductant in chemistry?

A reducing agent (also called a reductant, reducer, or electron donor) is an element or compound that loses or “donates” an electron to an electron recipient (called the oxidizing agent, oxidant, or oxidizer) in a redox chemical reaction.

What is reductant Class 11?

A substance which loses electrons to other substances in a redox reaction and gets oxidized to the higher valency state is called a reducing agent. A reducing agent is one of the reactants of an oxidation-reduction reaction which reduces the other reactant by giving out electrons to the reactant.

What is oxidant and reductant with example?

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.

Why is bih3 a strong reducing agent?

The nitrogen hydride is more stable and bismuth hydride is least stable. Due to the least stability of bismuth hydride, it is the strongest reducing agent among all the hydrides of group \[15\] elements.

Which is the reductant in this reaction?

( Cuo). as the copper is reduced from copper oxide so copper oxide is reducing agent.

How do you identify oxidant and reductant?

Break the reaction down into a net ionic equation and then into half-reactions. The substance that loses electrons is being oxidized and is the reducing agent. The substance that gains electrons is being reduced and is the oxidizing agent.

What is strongest reducing agent?

Lithium, having the largest negative value of electrode potential, is the strongest reducing agent.

Is reduction loss of hydrogen?

Oxidation is the loss of electrons, gain of oxygen or loss of hydrogen. Reduction is the gain of electrons, loss of oxygen or gain or hydrogen.

What is meant by oxidant?

noun, plural: oxidants. (1) Any substance that has the ability to oxidize other substance. (2) A molecule or atom capable of accepting electrons during a redox reaction. Supplement. An oxidant is a substance that accepts or receives electron from another substance, hence, is consequently reduced.

Why is BiH3 the strongest?

This is because as we move down the group, the size increases, as a result, length of E-H bond increases and its strength decreases, so that the bond can be broken easily to release H2 gas. Hence, BiH3 is the strongest reducing agent.
