Why does copper sulfate change its colour when water is added
If the water being added is pure, and the solvent in the copper sulfate solution was water, then no, this should not result in a chemical reaction. The visual change is due to dilution of the solute
The reaction forms aluminum sulfate and frees copper.
When Ammonia solution is added to Copper sulphate, at first a precipitate of Copper hydroxide is formed. If excess ammonia is added, finally a deep bluish solution of Tetraamine Copper(II) Sulfate is formed
It forms a complex - Copper (tetraamine) sulfate which is a deep inky blue color

The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.

Anhydrous copper sulfate solid is white. When it is added to water, it dissolves and the solution of aqueous copper sulfate becomes blue.
Its sulphate not sulfate and sorry im not sure my self
The pink precipitate is finely divided copper, reduced to its metallic form by displacement from copper sulfate by iron, which is higher in the electromotive series than copper. Iron sulfate remains in solution.
The solution will turn yellow
A solution is a mixture of any two substances, usually a liquid. Copper sulphate and water is a solution. There are many other solutions as well. Water and milk is a solution, mixing chemicals. Any mix of materials is technically a solution.
When an iron nail is dipped in the copper sulfate solution then iron displaces copper from the copper sulfate because iron is more reactive than copper.
