Question

Describe the process of making copper
sulphate crystals​

Answer 1

Answer

Crystals of copper sulphate are prepared by the method of crystallization.

The process is as followed: 

Step 1: A cupful of water in a beaker is taken.

Step 2: Few drops of dilute sulphuric acid is added to it.

Step 3: Water is heated and when it starts boiling copper sulphate powder is added slowly while    stirring till no more copper sulphate powder dissolved in it.

Step 4: Solution is filtered and let it cool without disturbance. After some time the crystals of copper can be observed in it. 

hope this helps you!!^_^

Answer 2

Answer:

Crystals of copper sulphate are prepared by the method of crystallization. ... Step 3: Water is heated and when it starts boiling copper sulphate powder is added slowly while stirring till no more copper sulphate powder dissolved in it. Step 4: Solution is filtered and let it cool without disturbance.

Step by Step:

: Place some sulfuric acid in a conical flask and warm it in a water bath.

: Add a spatula of copper oxide powder to the acid and stir with a glass rod.

: Continue adding copper oxide powder until it is in excess.

: Filter the mixture to remove the excess copper oxide.

: Pour the filtrate (the copper sulfate solution) into an evaporating basin.

: Heat the copper sulfate solution to evaporate half of the water.

: Pour the solution into a watch glass and leave to allow all of the water to evaporate.

Result:

Record the appearance of the copper sulfate crystals, including their colour and shape.

Analysis:

Hydrated copper sulfate crystals should be blue and regularly shaped. Describe how your crystals compare to this description. Suggest an explanation for any differences.
