Question

Suggest a method to separate the components of the mixtures given below by a flowchart:
a) Sodium chloride and sulphur
b)Chalkpowder,iron fillings and naphthalene
c)Sand,water and mustard oil
d)Petrol and water
e)Sugar from aqueous sugar solution

Answer 1

Answer:

Explanation:

To separate the components we have to use the following methods:

A. First dissolve the mixture in water. Sodium chloride will dissolve then do the process of filtration.

B. First use magnetic Separation method to separate iron fillings. Then use sublimation method to separate naphthalene.

C. First use sedimentation method . Sand will settle at the bottom. Then by decantation separate sand. Then by evaporation separate oil from water.

D. Use a separating funnel. Petrol being lighter than water will float . And depending upon the densities these will get separated.

E. So the process of evaporation. Water and sugar will be separated.

NOTE:- Sublimation is the process of converting a solid directly into gas or vice-versa.

Hope you got it. And it helps you. Please mark this as brainliest.
