Question

A)define activity series of metals.Arrange the metals gold,copper,iron and magnesium in ordr of their increase in reactivity. B)what will you observe when 1)some zinc peices are put in copper solution solution 2)some silver peices are put into green coloured ferrous sulphate solution

Answer 1

A ) activity series of metal means arrangement of different metals in vertical column , in order of decreasing reactivity of the metals .

Gold< Copper < Iron < Magnesium.

B) 1) Zn + CuSo4 = ZnSo4 + Cu
2) Ag + FeSo4 = No reaction because Fe is more reactive than Ag.

hope this helps you .....pls mark as brainlist !!!!
