Reduction is the gain of electrons. This can be an element which is becoming a negative ion, or a positive ion which is being turned into a free element. There are other possibilities, but these are the easiest to think of. The name 'reduction' originally referred to the reduction in mass when ores like iron ore were purified into a pure metal. The removal of other elements that the metal was chemically combined with produced pure metal with a reduced weight compared to the ore.

This results in a decrease in the number of positive charges on the atom or molecule. Reduced substances are often involved in redox reactions where they act as electron acceptors.


Why a substance that oxidised is called a reducing agent and why a substance that is reduced is called an oxidising agent?
