Multiple choices only one is correct
One of the agreements of the scientific community regarding the
electrochemical potentials is:
a) the standard hydrogen electrode acts as an anode
b) the potentials are expressed as a reduction
c) the sign of the reaction indicates the spontaneity of the
reaction
d) activity coefficients are always considered
Homework Answers
Ans : b) the potentials are expressed as a reduction
The electrochemical potentials of the species are expressed as their reduction potentials by default. So higher the reduction potential , more easily it will get reduced , and hence stronger will be the oxidizing agent.
So the species lying at the top of the electrode potential table are stronger oxidizing agents than the ones lying below them in the table.
