What is Redox Reaction?
When in any reaction, both process i.e., oxidation and reduction; happens simultaneously, that reaction is called a redox reaction.
For example, in zinc-copper cell
Oxidation Half-Reaction at Anode
Zn(s) → Zn2++2e–
Reduction of Half-Reaction at Cathode
Cu2++2e– → Cu(s)
To make metallic copper, zinc loses electrons that are grabbed by copper ions. The entire redox reaction between zinc and copper is:
Cu2++ Zn(s) → Cu(s) + Zn2+
The Redox Process in Zinc and Copper Cells was observed.
Redox Reactions and Electrode Processes
Electrode Potential and Standard Electrode Potential are key concepts in the field of electrochemistry which is the branch of chemistry that deals with relationships between electric potential differences and observable chemical change. Electrode Potential is also used extensively in the development of sustainable battery technologies, as all modern-day batteries work on this principle to create voltage for the smooth operations of electronic gadgets. This article deals with the topic of Electrode Potential and Standard Electrode Potential in detail and helps us understand how electricity or potential is produced using chemistry.
