Electrochemistry
1. Calculate the Electrode potential of Zinc electrode when it is dipped in Zn2+ solution of 0.015 M Concentration at 298 K. The standard Electrode potential (E°) is E° (Zn2+/Zn) = -0.76 V
2. (a) Using the electrochemical series, predict whether the following reaction will occur spontaneously at standard conditions:
Zn(s)+Cu2+(aq) → Zn2+(aq)+Cu(s)
(b) Justify your answer by calculating the standard cell potential for the reaction.
3.Discuss role of Electrochemical series in identifying suitable electrodes for electrochemical cells and batteries. Give examples of how this knowledge is applied in real-life applications like the lithium-ion battery.
