Question
A concentration cell consists of two Sn/Sn2+ electrodes. The electrolyte in compartment A is 0.21 M Sn(NO3)2. The electrolyte in B is 0.84 M Sn(NO3)2.
Which electrode is the cathode? (NOTE: Only ONE submission is allowed for this part of the question.)
Explanation / Answer
Electrode - B is acts as cathode
According to concentration cell principle more concentrated region acts as cathode and lessconcentrated region acts as anode.
0. 84M is high concentration part acts as cathode
0. 21M is low concentration part acts as anode.
