You could just memorize oxidation: lose electrons-reduction: gain electrons, but there are other ways. There are two mnemonics to remember which reaction is oxidation and which reaction is reductions. Oxidation and reduction reactions are common when working with acids and bases and other electrochemical processes.
Use these two mnemonics to help keep in mind which process is the oxidation and which is the reduction reaction. Actively scan device characteristics for identification.

Home Chemistry 10 differences between oxidation and reduction reaction.
When one molecule gains an electron is termed reduction. Meaning of the term Term oxidation means a reaction in which an element combines with oxygen. Term reduction means to lead back comes from Latin stem.
Agents involved An oxidizing agent oxidizes another substance and itself becomes reduced. It is also known as an electron acceptor. A reducing agent reduces another substance and itself becomes oxidized. It is also known as an electron donor.
Electron transfer In this, the electrons are lost. In this, the electrons are gained Hydrogen atom There is the removal of the hydrogen atom. There is an addition of the hydrogen group atom Oxygen atom When oxygen is added reaction releases energy. When oxygen is removed the reaction stores energy. Oxidation state Here the oxidation state increases. There is an increase in oxidation number Here the oxidation state decreases.
There is a decrease in oxidation number. It occurs in reducing agents. It occurs in oxidizing agents. It causes the increase of negative charges of chemical species. Real-life application Electrochemical reactions in batteries, photosynthesis, water splitting, etc Electrochemical reactions in nanoparticle synthesis by metal salt reduction, electrochemical cells, etc Difference between oxidation and reduction reaction What is a redox reaction?
This is called reduction reaction What is the difference between oxidation potential and reduction potential? What is the difference between oxidizing agents and reducing agents?
What are the common examples of oxidation reactions? Recent Posts. Azeotropes admin - November 4, 0. It contains two chemical species like an oxidizing agent and a reducing agent.
Oxidizing agent : It is defined as a substance that causes oxidation by accepting electrons. In a simpler way, an oxidizing agent is a substance that gets reduced. Reducing agent : It is defined as a substance that causes reduction by losing electrons. In a very simple way, a reducing agent is a substance that gets oxidized. Oxidation is the loss of electrons from a molecule or an atom or an ion which results in an increase in the oxidation state of the chemical substance. The old definitions of oxidation include loss of hydrogen or addition of oxygen.
As the loss of electrons occurs in oxidation there should be another chemical substance to accept electrons because the oxidation is known as oxidation half-reaction in the redox reaction.
Oxidation occurs by removal of hydrogen in the above example. It is also an example of oxidation of alcohol group into carboxylic acid group. Reduction is the gain of electrons from a molecule or an atom or an ion which results in the decrease of the oxidation state of the chemical substance.
