Two metallic element X and Y have following standard electrode potential: X=0.40 and Y=−0.80 V. What would you expect if element X was added to an aqueous salt solution of element Y? Give a reason for your answer.
john_gurung Have a look.
Electrode Potential of EX = 0.4
Electrode Potential of EY = -0.8
So, EY < EX or EX > EY
Hence, Metal X will displace metal Y from it’s salt solution.
