meaning oxidation and reduction..
Answers
Answer:
In Chemistry, it is referred to as the loss of oxygen when it is with respect to the oxygen transfer. It is the job of the reducing agent to remove the oxygen from another substance.
Similarly, in the case of hydrogen transfer, it is the gain of hydrogen. That means it is reducing agent’s work to remove oxygen from one substance and hydrogen to it.
Oxidation and Reduction in terms of Oxygen transfer
In early chemistry, oxidation and reduction were terms associated with oxygen.
Oxidation meant gaining oxygen and Reduction meant losing oxygen.
The term ‘reduction’ comes from Latin and means ‘-to lead back’.
Therefore anything that leads back to the free metal state is referred to as a reduction reaction.
Magnesium undergoes both oxidation and reduction in reactions with different reactants.
Oxidation And Reduction
Oxidation and Reduction in terms of Electron Transfer
This is the most commonly used definition of oxidation and reduction and most widely applicable.
In this case, Oxidation is the loss of electrons and Reduction is the gain of electrons.
A very clever mnemonic to remember this concept is oil rig.
OIL RIG
Oxidation is loss Reduction is gain
Oxidation and Reduction reactions are always interlinked. Because electrons are neither created nor destroyed in a chemical reaction, oxidation and reduction always occur in pairs, it is impossible to have one without the other. In the below reaction Magnesium gets oxidized by losing two electrons to oxygen which gets reduced by accepting two electrons from magnesium.
please mark as brainliest.......
Answer:
gain of oxygenand lose of hydrogen is oxidation and lose of oxygenand gain of hydrogen is reduction
