Copper sulfate is normally found in the form of blue crystals, copper (II) sulfate pentahydrate. When you heat copper sulfate pentahydrate it turns white as the water which is driven off by the heat. The white solid remaining is anhydrous copper sulfate. If you add water to the anhydrous copper sulfate an exothermic reaction occurs, you can feel the test-tube getting hot, as the blue copper sulfate pentahydrate is re-formed.

Anhydrous copper sulphate is a relatively stable compound (unlike the hydrated version, which if heated will lose water content) so you have to heat it quite a bit before anything happens; eventually it will melt.

What change will happen when copper sulphate is heated?

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.


What is The name of the copper sulphate after being heated?

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


What happens when you heat copper hydroxide and sodium nitrate?

When heat copper hydroxide and sodium Nitrate the pale blue precipitate change into black solid


What is formed when solid copper sulphate is mixed with water?

Take a cupful of water in a beaker and add few drops of dilute sulphuric acid. Heat water. When it starts boiling add copper sulphate powder slowly while stirring continuously. Continue adding copper sulphate powder till no more powder can be dissolved. Filter the solution. Allow it to cool. Do not disturb the solution after some time. We can see the crystals of copper sulphate. If we do not see any crystals, wait for some more time. Your copper sulphate crystal is ready. By: darani.a


Balance Copper 2 sulfate pentahydrate is heated to drive off the water hydration?

penta = 5 copper(II) sulphate pentahydrate = CuSO4*5 H2O CuSO4*5 H2O + heat --> CuSO4 + 5 H2O

Why is enthalpy of solution of 4g of anhydrous copper sulphate lower than the expected value?

Firstly, what do you mean by "lower"? Do you mean less exothermic? If that is what you mean, then one possible reason is that your anhydrous copper sulphate was not truly anhydrous, and that is highly likely. Did it look a bit blue? If so then it had absorbed some water from the air and therefore you did not weigh out as many moles of it as you had thought - hence less heat was released in your experiment.


What happens when add water to copper sulphate?

An exothermic reaction occurs (this is when heat is produced). There's a link between the mass of copper sulphate and the temperature rise of the water.


What is anhydrous copper sulphate?

The difference is that anhydrous copper(II) sulfate has no water of crystallisation. The anhydrous variant is a white solid while the hydrated variant is blue. Also, the chemical formula for hydrated copper(II) sulfate (or copper sulfate pentahydrate) is CuSO4.5H2O while that of the anhydrous one is CuSO4.


When Copper Sulphate is heated what is the observation?

When copper sulfate is heated the observation is that it turns white as the water which is driven off by the heat. It is also stated that the white solid will remain and if water is added to the anhydrous copper sulfate a reaction will occur.


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?
