Question

Why are Redox reactions used in batteries?

Answer 1

Hint: We can say that Electrochemistry is the investigation of how redox reactions can be utilized to build valuable tools, similar to batteries and electrolytic cells. Reactions in which electrons are moved are called oxidation-reduction (or "redox") responses. There are two sections to these changes: one particle should lose electrons and another atom should acquire them. These two sections are portrayed by the expressions "oxidation" and "reduction".

Complete answer:
In a battery, we run a redox reaction so that the oxidation and reduction half reactions are done in discrete containers. Thus, the electrons that move from the oxidized species to the reduced species can be made to go through a wire and to accomplish valuable work, similar to controlling a telephone.
We'll build a battery underneath utilizing two measuring glasses, yet the two half reactions can be isolated in an assortment of routes in genuine batteries.
Batteries are gadgets that, from a redox response, produce an electric flow. Fundamentally, the battery transforms chemical energy into electrical energy. The oxidation reaction happens on the negative anode, and electrons stream out of the cell.
Oxidation is the deficiency of electrons and an increment of electrons is a reduction. That is, oxidation is regularly associated with a lessening. In the case of something getting oxidized, the electrons are acquired by another species, going about as the oxidizing agent, and in the method is reduced.

Note:
We can say batteries are known as voltaic cells, electrochemical cells, (or) galvanic cells. Electrochemistry additionally assists us with doing things like comprehend and control the cycle of corrosion, plate metals on surfaces, and screen blood glucose levels, among numerous different applications.
