Question

What is crystallization? Give its two
applications.​

Answer 1

$\huge \boxed{ \bf \red{answer}}$

✔The process of crystallization is used to purify a solid from its impurities.

✔First of all, we take about 5 gram of impure sample of copper sulphate in a China dish.

✔After that, we dissolve it in minimum amount of water then filter the impurities.

✔Saturate the solution by heating that is when some solid starts evaporating.

✔Then we cover the solution with filter paper and leave it undisturbed to cool slowly for a day.

✔Hence, by this process we will obtain the crystals of copper sulphate in a China dish.

Answer 2

Answer:

Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.

Applications:---

i)Purification of drugs

ii)Improve bioavailability
