WebObservation no 1 :The solution will get colourless.Zinc will be replace with copper as zinc is more reactive than copper,and metallic copper will be accompanied in the bottom of the bekar. Reaction : Zn + CuSo4 ---->ZnSo4 + Cu WebCorrect options are B) and D) Positive value for Cu 2+/Cu indicates that this reduction takes place easily compared to H +/H 2. Hence, it is stronger oxidizing agent, i.e., (b) is correct. It also implies that Cu cannot reduce H + ions of an acid to H 2. Solve any question of The d and f Block Elements with:-.
