Which one of the following metals could not be obtained on electrolysi – InterviewSolution

1.	Which one of the following metals could not be obtained on electrolysis of aqueous solution of its salts
Answer» `AG` `MG` `Cu` `CR` Solution :The reduction potential of Mgis less than that of water `(E^(o)=-0.83V)`. Hence their ions in the aqueous solution cannot be REDUCED instead water will be reduced. `2H_(2)O+2e^(-)toH_(2)+2OH^(-)`.
