Sodium sulfate solution is neutral; the red litmus is purple.
Calcium sulfate is very low soluble in water - 2,1 g/L at 20 0C.
When lead is added to copper sulfate solution, a displacement reaction occurs where lead displaces copper from the solution to form lead sulfate and copper metal. This reaction is driven by the relative reactivity of the metals, with lead being more reactive than copper. The solid lead sulfate formed can be observed as a precipitate in the solution.
Iron can displace copper in a chemical reaction because it is a more reactive metal. When iron is added to a copper sulfate solution, the iron atoms will replace the copper atoms in the solution, forming iron sulfate and causing copper metal to be deposited. This process is known as a displacement reaction.

Why does copper sulfate change its colour when water is added
Sodium chloride solution is corrossive for aluminium; first a layer of of aluminium oxide is formed.
When copper sulfate is added to water, it dissociates into copper ions and sulfate ions. The copper ions give the solution a blue color, while the sulfate ions do not impact the color. The solution becomes a blue color due to the presence of copper ions.
The color of the copper sulfate solution changes from blue to colorless when zinc granules are added to it. This is because zinc displaces copper in the solution through a chemical reaction, forming zinc sulfate and leaving the solution without copper ions responsible for its blue color.
When copper sulfate is added to water, it dissolves and forms a blue solution. The copper ions (Cu2+) and sulfate ions (SO4 2-) are dispersed in the water, making a homogeneous mixture. This solution can be used for various applications, such as in agriculture as a fungicide or in chemistry experiments.
Sulfate ions in a solution are verified by adding BaCl2. If an acid was not added, it might be confused with BaCO3, if the solution has carbonate ions.
When ammonium sulfate is added to a protein solution, it disrupts the protein's structure by reducing the solubility of the protein. This causes the proteins to aggregate and precipitate out of the solution.
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
Sodium sulfate solution is neutral; the red litmus is purple.
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
