zinc granules will have their colour changed to brownish black in colour.
Nothing
Formation of a copper sulfate solution in water. This solution has a herbicide and fungicide effect.
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)
silicate, carbonate or sulphate
It isn't displaced as gold is less reactive than copper sulphate!
the solution turns green and the nails develop a brown deposit which is copper. the iron displaces the copper in the copper sulphate solution. This is because iron is more reactive than copper.

Copper Sulphate mixed with hot water makes Copper Sulphate Crystals.
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron.

an aqueous solution of copper sulphate is homogeneous
silicate, carbonate or sulphate
Yes, copper sulphate(CuSO4) can be separated from its solution in crystalline form.
It isn't displaced as gold is less reactive than copper sulphate!
no reaction would take place

When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour.Therefore, the blue colour of copper sulphate solution fades and green colour appears.
