write an experiment to shiw the presence of water in hydrated copper sulphate. ITS IS SO IMPORTANT...PLS GIVE CORRECT ANS...OTHERWISE I'LL BLOCK & REPORT

Answer:
AIM - To determine the water of crystallization.
Materials needed - copper sulphate crystals, test tube holder, burner, boiling tube.
Procedure - Heat few crystals of copper sulphate in a dry boiling tube.
-we will observe that on heating blue crystals of copper sulphate, it becomes colourless and few drops of water are seen on the test tube.
- Then, on adding few drops of water to the heated copper sulphate, the blue colour of copper sulphate reappears.
the water of crystallisation is the fixed number of water molecules present in one formula unit of salt.
Another simple procedure is-
By adding a little bit of HCl and heating it, the presence can be tested
While heating if vapour is formed in the test tube and the blue crystal turns white, then the sample is hydrated
Which means its Copper Sulfate Penta hydrate [CuSO4 . 5H2O] , i.e, due to presence of water.
Hope that helped.
Answer:
2% copper sulphate solution dissolve 2GMs of copper sulphate in hundred ml of water 10% of sodium hydroxide solution desolves 10 grams of sodium hydroxide in hundred of water
The substance that have taken that solied and grind and add 10 drops of water t powder and stir well and copper Sulphate
result
when the colour of food change into blue and purple it mean what is present in the components of food egg upper layer is present protein by this experiment we can say that is the egg proteins are present
