Answer 2

Answer:

a.the solution changes from blue to colourless.

c.the colour of the solution changes from blue to colourless.

e.When zinc is added to the solution of iron sulphate, the colour of iron sulphate solution changes. It is because zinc is more reactive than iron, therefore, it displaces iron from its solution of iron sulphate and a grey precipitate of iron and

a colourless solution of zinc sulphate is formed

b.iron is more reactive than copper. In this reaction, metallic iron is converted into ferrous ion (Fe2+) and cupric ion (Cu2 +) is converted into metallic copper.

d.Zinc displaces copper, and iron from their solutions. Zinc is more reactive than Cu and Fe metal. Iron displaces copper from its solution

f.Rust is an iron oxide, a usually reddish brown oxide formed by the reaction of iron and oxygen in the presence of water or air moisture .
