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.

∙ 7y agoIf a substance is reduced it means that it has gained electrons, so has a more negative charge so its 'positivity' has been reduced. Chlorine when reduced will form chloride ions but Potassium ions K+ when reduced will form Potassium metal.

In a "reduction reaction" an element or compound molecule has a "gain" in electrons that results in a lower oxidation state. It is the opposite of an "oxidation reaction" wherein the element (or compound) loses electrons and has an increase in oxidation state.
For example, elemental carbon undergoes reduction when it combines with hydrogen to form methane gas. Also, benzene is reduced (also gains electrons from hydrogen) when it forms cyclohexane.

Why a substance that oxidised is called a reducing agent and why a substance that is reduced is called an oxidising agent?
It is because when a substance is oxidized, it loses electrons which are taken up by other so that is gets reduced.This is why it is called reducing agent. Similarly, the substance reduced is called oxidizing agent.
What does foreign substance mean?
A foreign substance is some substance or material that does not belong where it is, such as a rock in your cereal.
What does Pure Substance mean in science?
I substance that made of only one element, to make a substance.
What does solubillity mean?
Solubility indicates how completely a substance dissolves into another substance.
Is oil and water is substance or element?
A mixture of oil and water is a mixture, not an element. If by substance you mean not a pure substance (element or compound), then oil and water would be a substance (that is a mixture). If you mean oil and water separately, then oil is a mixture of hydrocarbons, and water is a compound (pure substance).
What is the relationship between oxidising agent and the reduced substance?
Its the substance reduced which is termed to be an oxidizing agent. When a substance is reduced, it loses electrons that are taken up by another substance thereby oxidizing another substance (oxidising agent).
When a substances gains electrons is it reduced?
Yes when any substance gains electrons , that substance is now then reduced.
A substance that can not be reduced to a simpler substance by chemical means?
An "element"
What does cinders mean?
# A burned or partly burned substance, such as coal, that is not reduced to ashes but is incapable of further combustion. # A partly charred substance that can burn further but without flame.
What does monism mean?
View of all the reality is one unified divine reality. All the reality can be reduced to one "thing" or "substance".

What substance is transported as reduced hemoglobin in the blood?
Hydrogen Ion :-)
The substance that accepts electrons from another substance is the?
In a redox reaction, the substance that accepts electrons is said to be the substance reduced. This substance is also likely the oxidizing agent, since oxidation is the loss of electrons.
What substance is reduced in a lead storage battery?
The substance that is reduced in a lead battery as it generates electric currents is lead dioxide. You can recharge the battery by reversing the direction the current is flowing.
How can you determine whether a measured value of a substance represents an extensive property?
Its value will be reduced as the numbers of moles of the materials is reduced
Is the volume of substance the same before and after a fire?
no the volume can be greatly reduced
What substance is reduced in a lead-acid storage battery?
lead oxide
