Question

why cannot displacement reaction in zinc sulphate and iron sulphate solutions take place on adding copper turnings?

Answer 1

answer : because Copper is lower reactive than Zinc and Iron.

explanation : in displacement reaction, a higher reactive element displaces a lower reactive element from its compound.

i.e., $A+BC\rightarrow AC + B$

here , A is higher reactive element than B. that's why B is displaced by A.

here, $ZnSO_4+Cu\rightarrow\textbf{no reaction}$ , because Zn is more reactive than Cu.

similarly, $FeSO_4+Cu\rightarrow\textbf{no reaction}$ because Fe is more reactive than Cu.

Answer 2

Answer:-

because Copper is lower reactive than Zinc and Iron.

explanation :

in displacement reaction, a higher reactive element displaces a lower reactive element from its compound.

i.e.,

$A+BC\rightarrow AC + BA+BC→AC+B$

here , A is higher reactive element than B. that's why B is displaced by A.

here, ZnSO_4+Cu\rightarrow\textbf{no reaction}ZnSO

4

+Cu→no reaction , because Zn is more reactive than Cu.

similarly, $FeSO_4+Cu\rightarrow\textbf{no reaction}FeSO </p><p>4$

+Cu→no reaction because Fe is more reactive than Cu.
