Question

What is crystallization? How can you prepare crystals of copper sulphate from an impure sample
of it?​

Answer 1

Answer:

Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. we can prepare using filtration.Pure copper sulphate can be obtained from an impure sample by re-crystallization. The impure sample is dissolved in water, heated and then cooled which then later forms crystals. These copper sulphate crystals are then separated by filtration and drying.

Answer 2

Explanation:

Crystallization is defined as a process by which a chemical is converted from a liquid solution into a solid crystalline state.

• Copper sulphate crystal is prepared by crystallization method as follows:

• Take a cupful of water in a breaker and a few drops of dil.H2so4,heat and water

• When it starts boiling, add CuSo4 powder slowly continue to add cuso4 powder till no more powder can be dissolved
• During this process, Continuously stir the solution. Filter the solution.

• Leave it for cooling look it after some time, you can see the crystals of copper sulphate.
