they dissolve or dilute
When blue copper sulphate is heated, it loses water molecules and converts to anhydrous copper sulfate, which is white in color. The blue color of copper sulfate is due to the presence of water molecules in its crystal structure.
When blue copper sulfate crystals are heated, the water of crystallization evaporates, turning the blue crystals white. This is due to the loss of water molecules, resulting in anhydrous copper sulfate.
Hydrous copper sulphate, when heated, turns into anhydrous copper sulphate and changes its color from blue to white. The blue color comes from the water molecules bound to the copper sulphate crystals, and when heated, these water molecules are removed, resulting in a color change.
copper sulphate is a beautiful blue crystal [and yes it is spelt Sulphate not Sulfate]
When copper sulfate crystals are heated, they lose their water of hydration and turn into anhydrous copper sulfate, which is a white powder. The color change from blue to white signifies the removal of water molecules.
When a crystal of copper sulfate is strongly heated, it undergoes dehydration and turns into anhydrous copper sulfate, leaving a white residue. This white residue is the anhydrous form of copper sulfate, which has lost its water molecules during the heating process.
The reaction is;CuSO4 = CuO + SO3
Hydrated copper sulphate (CuSO4.5H2O) is BLUE Anhydrous copper sulphate (CuSO4) is white at any temperature.
copper sulphate and hydrogen is released.
it is like the color but gold more
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.
The formula of the blue crystals of copper sulphate is CuSO4.5H2O. When they are heated mildly, the water from the crystals evaporate, giving just CuSO4. This 'anhydrous' form of copper (II) sulphate is white in colour.
