State which of the following chemical reactions will take place or not, giving suitable reason for each

Question: State which of the following chemical reactions will take place or not, giving suitable reason for each:

(a) Zn (s) + CuSO (aq) → ZnSO (aq) + Cu (s)

(b) Fe (s) + ZnSO₄ (aq) → FeSO (aq) + Zn (s)

(c) Zn (s) + FeSO (aq) → ZnSO (aq) + Fe (s) [CBSE, Term 1, Set 1, 2016]

Answer: (b) Fe(s) + ZnSO(aq.) → FeSO(aq.) + Zn(s)

This chemical reaction is not possible, because Zn is more reactive than Fe, so it cannot be replaced.


State which of the following chemical reactions will take place or not, giving suitable reason for each: (a) Zn (s) + CuSO₄ (aq) → ZnSO₄ (aq) + Cu (s) (b) Fe (s) + ZnSO₄ (aq) → FeSO₄ (aq) + Zn (s) (c) Zn (s) + FeSO₄ (aq) → ZnSO₄ (aq) + Fe (s) [CBSE, Term 1, Set 1, 2016]
