What colour does hydrous copper sulphate turn when heated?
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.
What type of change happens when you heat copper sulfate?
When you heat copper sulfate, it undergoes a physical change where it loses its water of hydration, turning from blue crystals to a white powder (anhydrous copper sulfate). This change is reversible, as adding water to the white powder will turn it back to blue crystals.
Why does the copper sulphate powder turn blue and gets hot when add water to it?
When water is added to copper sulfate powder, it dissolves to form a solution. This dissolution is an exothermic process, meaning it releases heat, causing the solution to become warm. The blue color of the solution is due to the copper ions in the copper sulfate forming a blue complex with water molecules.
What happens when you heat copper sulfate crystals?
When heated, copper sulfate crystals lose their water molecules and turn into anhydrous copper sulfate, releasing steam in the process. The color of the crystals changes from blue to white as they lose the water.
When copper sulphate reacts with iron what colour does it turn?
When copper sulphate reacts with iron, the solution turns blue due to the formation of copper ions in the solution. This is because copper is displaced from the copper sulfate and iron sulfate is formed, leading to the blue color of the solution.

When mixed with water why does copper sulphate turn water blue?
because when in a solution it forms blue crystals creating a blue colour
Why does copper sulphate turn blue when water is added?
The copper sulfate reacts with the water, creating a new substance with a different color.
What colour does copper sulphate turn the universal indicator?
Copper sulfate will turn universal indicator blue or purple due to its acidic nature.
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 blue crystals of copper sulphate on heating turn colourless?
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.
What is the colour of copper sulphate crystals before and after heating?
Copper Sulphate crystals before heating r blue....but after heating I dunno , may be u should try and ask your Sci.Miss/Sir I'll get back when I get the other answer .
Why does copper sulphate solution not evaporate when heated?
When heated blue copper sulphate solution does evaporate!!!! The result is BLUE copper sulphate crystals of the penta-hydrate (CuSO4.5H2O). If you continue to heat these blue crystals, they will turn white in colour as you drive off the water of hydration. CuSO4.5H2O(s)(Blue) ==heat==> CuSO4(s)(white) + 5H2O(g) The analogy of hydration is like holding a ball in your hand. Your hand is the copper sulphate, and the ball is the water. Open your hand (heat) and the ball falls away(water is released). Your hand and the ball remain separate objects (NOT combined). Similarly the copper sulphate and the water remain separate molecules (NOT combined). It's just that the one is held (in the crystal lattice), by the other.,
