Question : 5 of 36

Marks: +1, -0

Reverse of the following chemical reaction is not possible :

{\Zn}( {\ s})+ {\CuSO}_4( {\aq}) → {\ZnSO}_4( {\aq})+ {\Cu}( {\ s})

Justify this statement with reason.

Solution:

Most reactive metal displaces less reactive metals since

{\Cu}

is less reactive than

{\Zn}

so it will not displace

{\Zn}

from

{\ZnSO}_4

{\ZnSO}_{4( {\aq})}+ {\Cu}_{( {\ s})} → \;\text " No reaction "\;
