Question

Give reason a copper cannot displace zinc from its salt solution b)What happens when iron nails are placed in copper sulphate solution?

Answer 1

Answer:   copper cannot displace zinc from its salt solution

beacus zinc is more reactive than cooper so copper is less reactive so it cannot displace zinc

b)

it turn to iron sulphate and copper is librated

Explanation:

Answer 2

Answer:

1:-) Give reason a copper cannot displace zinc from its salt solution

=:- In the reactivity series, zinc is more reactive than copper. A more reactive metal can replace a less reactive metal, but a less reactive metal cannot replace a more reactive metal. Thus, copper cannot displace zinc from its salt solution, while zinc can displace copper from its salt solution.

2:-)What happens when iron nails are placed in copper sulphate solution?

=:- When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed on the surface of iron and the colour of copper sulphate solution changes from blue to light green.
