What happens when water comes in contact with white copper sulphate crystals?
Benpoarchfb5423
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 equipment would be needed to prepare copper sulphate crystals?
Anhydrous or hydrated copper sulphate crystals? And from what?
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.
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.
Which methods is used to obtain pure copper sulphate from impure sample and how?
by crystallisation, we can get pure copper sulphate crystals
Are copper sulphate crystals good conductors of electricity?
no

What happens when copper sulphate is dissolved in water?
Copper Sulphate mixed with hot water makes Copper Sulphate Crystals.

Do copper sulphate crystals have cleavage planes?
yes they do

no
Can copper sulphate crystals dissolve in water?
yes
What happens when copper sulphate is mixed with sand?
It turns to smaller crystals and is covered with the sand. Also it can be retrieved from sand easily.
Are copper sulphate crystals soluble?
Yes, in a saturated copper sulfate solution.
What effect would dissolving some copper sulphate crystals in the water have on its boiling point?

What colour are copper sulphate crystals?
very dark blue
