What is different between standard electrode potential and standard reduction potential?

Open in App

Solution

Standard electrode potential is the sum of the reduction and oxidation potential of the respective electrodes measured at standard condition. Standard reduction potential is the potential difference between the cathode and its solution, in which reduction occur. This is also measured at the standard condition.
Standard electrode potential E⁰ = E⁰_ox + E⁰red
Standard condition = 1 M solution and 25 ⁰C
