what is electrode potential
Answers
Answer:
Electrode Potential,E, in a chemistry or electrochmistry, is a electromotive force of all cell built of two electrodes. On the left hand side the cell diagram is standard hydrogen electrodes(SHE) and on the right hand side is electrode in question.
The SHE is defined to have a potential of 0 V so the singed cell potential from the above
E ᴄᴇʟʟ = E ʟᴇғᴛ (sʜᴇ) - E ʀɪɢʜᴛ = 0 V - E ᴇʟᴇᴄᴛʀᴏᴅᴇ = E ᴇʟᴇᴄᴛʀᴏᴅᴇ
Electrical potential (commonly known as voltage) is the strength of the push or pull on electrons by the reactants in a redox reaction (reaction that involves transfer of electrons).
It is of two types —
- Oxidation potential
- Reduction potential
When electrode is negatively charged with respect to solution that is it acts as anode.The oxidation take place.
When electrode is positively charged with respect to solution that is it acts as cathode.The reduction take place.
