Question

3. Which of the following statement is not correct?
a) Copper is unable to displace zinc from zinc sulphate
b) Copper is unable to displace iron from iron sulphate
c) Iron is unable to displace zinc fromzinc sulphate
d) Iron is unable to displace copper from copper sulphate Solution​

Answer 1

Answer:

iron is unable to displace copper from copper sulphate solution.

make me as a braniliest. please please....

Answer 2

Answer:

Statement D is not correct.

Explanation:

a) Zinc displaces copper from copper sulphate solution to form zinc sulphate and metallic copper but copper does not displaces zinc from zinc sulphate. This is because zinc is placed above the copper in the Reactivity Series of metals.

b) copper cannot displace iron from iron sulphate because in displacement reaction more reactive metal displaces less reactive metal from its salt solution, but iron is more reactive than copper.

c) Iron cannot displace zinc from the zinc sulphate because zinc is more reactive metal . More reactive metal can displace less reactive metal from its salt solution.

d) Iron displaces copper from copper sulphate solution but copper cannot displace iron from iron sulphate solution because court is less reactive than iron.
