Reducing Agent

Quick Reference
Also Known AsReductant, electron donor, reducer

What is Reducing Agent?

A substance that donates electrons to another species in a redox reaction, causing that species to be reduced. The reducing agent itself is oxidized in the process. Examples include metals, hydrogen, carbon monoxide, and sulfur dioxide.

Properties & Characteristics

A reducing agent is a substance that donates electrons to another species in a redox reaction, becoming oxidised itself. Common reducing agents include hydrogen gas, carbon, and metals. The strength of a reducing agent is related to its standard electrode potential. Strong reducing agents have highly negative reduction potentials.

Uses & Applications

Reducing agents are used in metallurgy to extract metals from their ores (e.g., coke reducing iron ore). They are used in organic synthesis to reduce functional groups. Industrial reducing agents like hydrogen are used in the Haber process and hydrogenation reactions.

Safety Information

Many reducing agents are flammable or pyrophoric (e.g., lithium aluminium hydride, sodium borohydride). They should be handled under inert atmospheres and kept away from oxidising agents to prevent fire or explosion.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
