Question

explain what happens when zinc reacts with copper sulphate.

Answer 1

$\huge{\mathcal{\underline{Answer}}}$

$<font color ="pink"><i>$When zinc metal is immersed in a solution of 0.1 M aqueous copper(II) sulfate solution copper metal plates out on the zinc. The solution is initially blue in color. A dark coating of copper metal appears on the zinc within two minutes and when 45 minutes have elapsed, there is a thick coat of copper metal powder on the zinc strip and the blue color of the solution has lightened considerably.

Zn(s) + Cu2+(aq) -> Zn2+(aq) + Cu(s)

Zinc atoms are oxidized to Zn2+(aq): Zn(s) -> Zn2+(aq) + 2e- (loss of electrons)

Copper(II) ions are reduced to Cu(s): Cu2+(aq) + 2e- -> Cu(s) (gain of electrons)

This demonstration should also include having students predict whether or not copper will react with ZnSO4(aq).

Cu(s) + Zn2+(aq) -> No reaction

Zinc is a more active metal compare to copper. The Zn2+(aq) ions do not serve as a reducing agent.

This is a great demo to present at the beginning of a unit on electrochemistry because it can be followed later in the unit by the zinc/copper cell demo. This demo can also be used when discussing single-replacement reactions, redox reactions, or electronegativity.

Answer 2

Heya here is the ans of your qun ....

Zn(s) + CuSO4 = Cu (s) + ZnSO4 (aq)

explanation

when when zinc reacts with copper sulphate zinc displaces copper from copper sulphate and form zinc sulphate form sollution ...

hope it helps u
