Study the effect of heat on hydrated copper sulfate. Why does this salt look colored, and why does it lose color upon heating?
Hydrated copper sulfate (CuSO₄·5H₂O) is blue in color due to the presence of water molecules in its crystalline structure. The water molecules form a complex with copper ions, which gives the crystal its characteristic blue hue. When heated, the water evaporates, and the salt loses its blue color. This is because the removal of water … Read more
