A light green coloured solution of sulphate salt of metal 'P' is taken in a beaker, a rod of another metal 'Q' is put in this solution as shown the following figures :
Identify the metals 'P' and 'Q' and write its chemical equation for the reaction that occurs. State the conclusion of this reaction in terms of reactivity series of metals.
Solution
P – Fe
Q – Zn / Mg
Chemical reaction:
FeSO4 + Zn → ZnSO4 + Fe / FeSO4 + Mg → MgSO4 + Fe
More reactive metal will displace less reactive metal from its salt solution. / Zn or Mg are more reactive than Fe.
