I have also done that gcse paper and I put down copper as the pink brown solid, it might also be worth mentioning that I am one of the best at chemistry in my class
The reddish-brown coating formed on the iron nail when placed in a copper sulfate solution is due to a chemical reaction called displacement. In this reaction, the iron displaces copper from the copper sulfate solution, forming solid copper on the iron surface, giving it a reddish-brown appearance.
The chemical equation for this reaction is: Fe(s) + CuSO4(aq) -> FeSO4(aq) + Cu(s).Iron displaces copper from copper sulphate solution to form iron sulphate and solid copper precipitates out of the solution. This is an example of a single displacement reaction.
If you drop a piece of magnesium ribbon into copper sulphate solution, you would observe a redox reaction where the magnesium displaces the copper in the solution. This results in the formation of copper metal and magnesium sulphate, with a color change from blue to colorless as the reaction progresses. Additionally, there may be bubbling and fizzing observed as the reaction occurs.
When barium sulfate reacts with copper sulfate, a double displacement reaction occurs. Barium sulfate and copper sulfate exchange ions to form barium sulfate and copper sulfate precipitates. The reaction results in the formation of a white solid of barium sulfate, which is insoluble in water.
If you add copper sulfate to sodium hydroxide, a double displacement reaction will occur. The copper sulfate will react with the sodium hydroxide to form copper hydroxide, which is a blue solid, and sodium sulfate, which is a soluble compound. This reaction is often used in qualitative analysis to test for the presence of copper ions.

The reaction between copper sulfate and zinc can be represented by the following equation: CuSO4 + Zn -> ZnSO4 + Cu. In this reaction, zinc replaces copper in the copper sulfate solution, resulting in the formation of zinc sulfate and solid copper.
The reaction takes place resulting in the formation of Iron sulphate(light green coloured) and copper(solid). The equation is :- Fe(s) + CuSO4(aq.) ------------> FeSO4(aq.) + Cu(s)
Aqueous copper sulfate solution contains free ions (Cu2+ and SO4 2-) that can carry electrical charge and allow the solution to conduct electricity. In contrast, solid copper sulfate does not contain free ions and is unable to conduct electricity because the ions are locked in a fixed position within the solid lattice.
Copper can be released from a copper sulfate solution by electrolysis or by adding a more reactive metal, such as iron or magnesium, which will displace the copper in a single replacement reaction. Another method is to heat the solution to evaporate the water, leaving behind solid copper sulfate which can then be reduced to obtain copper metal.
Copper is a reddish-brown metal that is solid at room temperature. So, it is more accurate to describe copper as a reddish-brown solid rather than just a brown solid.
This is due to something called a displacment reaction, during a displacment reaction one of the particals from one of the substances "swap" with another partical from the solution In the case of zink and copper sulphate solution, the copper and zink 'switch places to produce copper and a solution of zink sulphate. This is how, A + BC = B +AC
The precipitate formed when copper sulfate and sodium carbonate are mixed is copper carbonate. This reaction occurs because copper carbonate is insoluble in water and therefore forms a solid precipitate.
