What does redox potential mean?
The measure of the tendency of a chemical species to acquire electrons and thereby gets reduced is called redox potential.
The standard redox potential for reactions Mn2++2e -----> Mn and Mn3+ +1e -----> Mn2+ are 2.36 and 1.51V respectively . What is the redox potential for the reaction Mn3++3e------> Mn ?
What does potential difference in a capacitor really mean? Is it the work done in bringing Q charge from infinity?
