The substance turns white then grey and finally brown. That is because heat is given off and water evaporates.

โ 13y agoWhen heated, copper II sulfate pentahydrate decomposes to form anhydrous copper II sulfate and water vapor. The water molecules bound in the crystal structure are released as steam, leaving behind a white residue of anhydrous copper II sulfate powder.
The balanced equation for the heating of copper(II) sulfate pentahydrate (CuSO4โข5H2O) is: CuSO4โข5H2O(s) -> CuSO4(s) + 5H2O(g). This reaction decomposes the pentahydrate compound into anhydrous copper(II) sulfate and water vapor.
When copper II sulfate pentahydrate is heated, it decomposes to form anhydrous copper II sulfate. The appearance of the resulting liquid is a clear, colorless solution. It does not have a specific odor.
When heating copper(II) sulfate pentahydrate, the water molecules in the crystal structure are removed, leaving anhydrous copper(II) sulfate. The balanced chemical equation for this reaction is CuSO4ยท5H2O(s) โ CuSO4(s) + 5H2O(g).
When you heat anhydrous copper sulfate (CuSO4), it undergoes a color change from white to grayish-white due to dehydration. The anhydrous copper sulfate starts to release water molecules as it forms the hydrated form of copper sulfate.
It becomes a non-crystalline, powdery anhydrous salt.The hydrated (pentahydrate) form is chalcanthite, a bright blue crystal. The rare anhydrous ore form is called chalcocyanite, a gray or pale-green powdery rock.(If heated to 650 °C, copper sulfate becomes copper oxide and sulfur trioxide.)
When copper sulfate pentahydrate is heated, the water molecules are driven off, leaving anhydrous copper sulfate as the solid residue. The chemical equation for this reaction is: CuSO4*5H2O(s) โ CuSO4(s) + 5H2O(g).
When copper sulfate pentahydrate is heated, it undergoes a dehydration reaction where the water molecules are released, leaving behind anhydrous copper sulfate. This process is reversible, and when anhydrous copper sulfate is exposed to moisture, it will reabsorb water and form copper sulfate pentahydrate again.

When you heat anhydrous copper sulfate (CuSO4), it undergoes a color change from white to grayish-white due to dehydration. The anhydrous copper sulfate starts to release water molecules as it forms the hydrated form of copper sulfate.
When copper II sulfate pentahydrate is heated, it loses its water molecules through evaporation. The removal of these water molecules changes the structure of the compound, resulting in the loss of the blue color. Without the water molecules, the compound forms anhydrous copper II sulfate, which is white in color.
Adding water to heated copper sulfate crystals is a chemical change. When water is added to heated copper sulfate crystals, the copper sulfate undergoes a chemical reaction where it dissolves in the water to form a solution. This is a chemical change because the chemical composition of the copper sulfate is altered during the process.

The chemical equation for the reaction of copper sulfate when heated is: CuSO4 (s) -> CuO (s) + SO2 (g) + O2 (g). This reaction involves the decomposition of copper sulfate into copper oxide, sulfur dioxide, and oxygen gas.
When copper sulfate is heated, it decomposes to form copper oxide and sulfur dioxide gas.
