Question

what is fractional distillation and what is colloidal solution ????? plz tell it's urgent.. plz tell fast

Answer 1

Fractional distillation is a process of separating a mixture of chemical compounds. This means that each part (called a "fraction") of the mixture can be kept apart from the other chemicals.

A colloidal solution, occasionally identified as a colloidal suspension, is a mixture in which the substances are regularly suspended in a fluid. A colloid is a minutely small material that is regularly spread out all through another substance.

I hope it will help you.

-: FRACTIONAL DISTILLATION :-

we know there are many methods to separate different types mixtures like salt from its solution. colors of dye etc.

now we have to separate two micible liquids, either we will use distillation or fractional distillation. distillation can be used when there's difference between the boiling point of the two liquid. but in fractional distillation, the difference between the boiling point of the two liquids must be less than 25k.

for example - fractional distillation process is used when gases are being separated from air.

in this method, a fractionating column is a tube packed with glass beads and the beads makes the surface for the vapours to condense repeatedly.

-: COLLOIDAL SOLUTION :-

colloids are hetrogeneous mixture but they seem like homogeneous mixture because the particles of colloids are very small and can't be seen through naked eyes. the particles are uniformly spread throughout the solution. but the particles can scatter the beam of light passing though it make the path visible.

the scattering of light is known as Tyndall effect and colloids shows Tyndall effect. for example :- smoke, fogg, milk etc.

and particles of colloids can't be separated by filter paper...
