Question

7) Complete the paragraph:
(ionic bond, copper (Cu), copper sulphate (CuSO4), breaks, zinc sulphate (ZnSO4), Zinc (Zn),
combines)
In the equation Zn + CuSO4 + ZnSO4 + Cu, ........... and
are reactants. They react with each
other to form
......... particles and a solution of colourless
as products. The ....... in
CuSO4.. and ionic bond in ZnSO4 is formed during reaction.
.......​

Answer 1

Answer:

Answer

Correct option is

A

copper

Zinc is more reactive than copper. So, on adding zinc to CuSO

4

solution it displaces copper from copper sulphate & forms zinc sulphate solution.

Zn+CuSO

4

→ ZnSO

4

+Cu

This is indicated by a colour change from blue to colourless. CuSO

4

solution has a blue colour while, ZnSO

4

solution is colourless.

Therefore, zinc displaces copper from CuSO

4

solution. The correct answer is copper.
