Any water soluble blue salt (and which does not react with water) can turn the solution blue. For example = Copper(II) sulfate[CuSO4], Oxovanadium(IV) sulfate[VOSO4], Copper(II) nitrate[Cu(NO3)2], etc.

Why does the copper sulphate powder turn blue and gets hot when add water to it?
Cuz it's copper sulphate
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 colour does hydrous copper sulphate turn when heated?
blue
What happens when you heat copper sulfate crystals?
they get warmer Blue Copper sulphate crystals contain a lot of water. If you heat them the water is driven off and they turn white.
What type of change happens when you heat copper sulfate?
Blue Copper sulphate crystals contain a lot of water. If you heat them the water is driven off and they turn white.
Why does the copper sulphate powder turn blue and gets hot when add water to it?
Cuz it's copper sulphate
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.
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.
Why does white copper sulphate turn blue when water is added?
The copper sulfate reacts with the water, creating a new substance with a different color.
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.
What colour does hydrous copper sulphate turn when heated?
blue

Blue Copper sulphate crystals contain a lot of water. If you heat them the water is driven off and they turn white.
Why when you heat up copper sulphate does it turn blue?
You have this backwards. Copper sulfate, CuSO4.5H2O is blue. When it is gently heated, it loses water and turns white.CuSO4.5H2O --> CuSO4 + 5 H2O.The white substance is anhydrous copper sulfate. If you put water on it it turns blue again.
What is the pool water dark after using copper sulphate?
the chlorine in the water oxidizes the copper causing an off color, if you used enough of each it would turn a greenish blue color.
Is copper oxide soluble?
copper sulphate is soluble in water - take the reaction to form blue crystals (sulphuric acid + copper carbonate) - once the water is evaporated off blue crystals are left. And if the water is evaporated off still the crystals turn white! so it must be.
