It turns into blueish clear crystals but only if u don't have a lid on it when it is heated!
add. as it is heated, the water of crystallization will be driven off, and soon you'll have a greenish powder.
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
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.
actually blue salt of copper sulphate is chemically copper sulphate penta hydrate( CuSO4.5H2O ). blue coloure is due to thiese 5 moles of water . by heating this water evaporates and leaving CuSO4 which is colourless
Copper Sulphate usually is found in a hydrated form (i.e., water molecules are incorporated into the crystals.) Pure copper sulphate is a pale, greenish gray color. The familiar blue color only occurs in hydrates of copper sulphate (i.e., in crystals that incorporate H20 molecules). Heating the blue crystals can drive off the water. It's still called copper sulphate after you do that. For substances like copper sulphate that naturally attract water, the adjective, anhydrous often is used to describe the pure (water free) state. If you heat copper sulphate to a temperature of 650C, it will decompose into something else. http://en.wikipedia.org/wiki/Copper_sulphate
When heated, copper sulfate undergoes a reversible physical change where it loses its water molecules (dehydration) and changes color from blue to white. This process is purely physical and does not involve any chemical reactions.
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.
Hydrated copper sulphate (CuSO4.5H2O) is BLUE Anhydrous copper sulphate (CuSO4) is white at any temperature.
they dissolve or dilute
The reaction is;CuSO4 = CuO + SO3
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 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.
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.
