Arrangement of displacement reaction is given in the picture. Here a metal rod is dipped in the salt solution of another metal. Equations of chemical reactions taking place here are given below. Mg rarr Mg^2+ 2e^- Zn^2+ 2e^- rarr Zn a) Which is the metal rod used here? b) If copper rod is used instead of the above metal rod, is displacement reaction possible? Give reason (hint: Order of reactivity of metals Ca gt Mg gt Al gt Zn gt Fe gt Cu) .
