Question

describe methods of separation and purification: filtration, crystalilsation, distillation, fractional distillation.

Answer 1

hi friend
here's your answer looking for

show all above that you have given is the process of separating one substance from another substances.

Let's discuss all you have written:-

=> Filtration :- it is a process by which we can separate out the bigger particle that is suspended in any liquid. this process can be done by the filter paper.


two separate out the bigger particle that is suspended in the liquid we have to follow the following steps:-

1). take the funnel and place the filter paper inside it.

2). and then pour the mixture that you want to separate it out.

3). the bigger particle will get separated by the filter paper.

Note:- a substance that you want to separate it out that means the solute must be bigger than the holes of filter paper.

=> crystallisation :- crystallization is the process which separate the the solid particles in the form of crystals from the solution.

so in this process the impure particles get separated from the solution in the pure solid form.

=> distillation :- it is a process by which we can separate out the two immiscible liquid that is mixed in a mixture.
this process is totally dependent upon the boiling points of the liquids that is mixed in it.

during this process when the mixture of two immiscible liquid is heated up, the liquid that has lower boiling point as compared to the another get first evaporated and then condensed to again form it in the liquid state. and at last we get that a liquid.

and a liquid that has higher boiling point that will be left inside the breaker.

Note :- the liquids that is mixed inside the mixture must have the difference of 25 degree in between their boiling points.


=> fractional distillation => it is a process by which we can separate out many invisible liquid that is mixed in a mixture.
it is same as a distillation process but here we separate this immiscible liquids by the fractionating columns.

this process also dependent upon the boiling point of the liquids that is mixed inside the mixture.

so in this process also a liquid that has lower boiling point will separate out first and then so on.
and at last we left the liquid in the beaker that is the highest boiling point in the whole mixture.


hope this all help you a lot.
