What color does anyhydrous copper sulphate turn when added to water?

Blue, because the copper cations become hydrated and the hydrated ions have a blue color.


Why does white anhydrous copper sulphate turn blue when water is added?

It turns blue because copper forms blue crystals when in solution. As soon as the water evaporates, there's nowhere for the copper to be in "solution", so it loses its colour. When water is added again, the crystals regain the "solution" state and turn blue!


Why does white copper sulphate turn blue when water is added?

White copper sulfate is anhydrous, meaning it does not contain water molecules. When water is added to white copper sulfate, it forms a hydrate compound called blue copper sulfate pentahydrate. The water molecules coordinate with the copper ions, causing the compound to change color from white to blue.


- What would happen to the anhydrous cupric sulfate if you added water to it?

Anhydrous cupric sulfate would form hydrated copper(II) sulfate when water is added to it. This process is exothermic and the anhydrous crystals would dissolve as the water molecules bond with the copper sulfate molecules to form a hydrated crystal structure.


Chemical reaction between calcium and copper sulphate?

When calcium metal is added to a solution of copper sulfate, a single displacement reaction occurs. The more reactive calcium displaces the less reactive copper from the copper sulfate solution. This results in the formation of calcium sulfate and elemental copper. The balanced chemical equation for this reaction is: Ca + CuSO4 -> CaSO4 + Cu.

When added to copper sulphate what colour is anhydrous copper sulphate?

anhydrous copper sulphate is white. when water is added it turns blue, in essence it can be used to detect the presence of water. hope this helps!!!!!!!!!!!


What colour is pure water when anhydrous copper sulphate is added and is there a soild residue?

Anhydrous copper sulfate solid is white. When it is added to water, it dissolves and the solution of aqueous copper sulfate becomes blue.


What happens when copper is added to copper sulphate?

Nothing


Why does the water colour change to blue when copper sulphate was added?

Anhydrous copper(II) sulphate is white. When added to water, it forms a solution of CuSO4(aq) which is blue because of the Cu2+ ion, which is itself a transition metal ion.


What happens when steel wool is added to copper sulphate?

Copper is deposed on the steel wool.


What happens to copper sulphate when added to water?

When copper sulphate is added to water, it dissociates into copper ions (Cu2+) and sulphate ions (SO4 2-). This forms a blue-colored solution due to the presence of copper ions in the water.


What happens when copper is added to concentrated sulfuric acid and heated gently?

copper sulphate and hydrogen is released.


What happens when water comes in contact with white copper sulphate crystals?

The white copper sulphate will become blue. This is because copper sulphate usually has 5 moles of H2O, but it has reached a temperature where all five moles will have detached themselves from the copper sulphate, so it will become anhydrous (without water) and white. Then, when water is added back to it, it returns to its original blue state.


What two things happen when zinc is added to copper sulphate?

The Zinc will displace the copper. It will become Zinc Sulphate. The word equation will be Zinc + Copper Sulphate -----> Copper + Zinc Sulphate. Hope this helps!


What colour does water change anhydrous copper sulfate?

When water is added to anhydrous copper sulfate, it forms copper (II) sulfate pentahydrate, a blue crystalline solid. So, the color change observed is from white (anhydrous) to blue (pentahydrate) when water is added.


Does copper sulphate dissolved in water?

Yes, copper sulphate can dissolve in water. When added to water, copper sulphate dissociates into copper ions (Cu2+) and sulphate ions (SO4 2-), forming a blue-colored solution.


What color does anyhydrous copper sulphate turn when added to water?

Blue, because the copper cations become hydrated and the hydrated ions have a blue color.
