Question

A mixture contains only Iodine , Ammonium chloride and sand. Only Iodine and nAmmonium chloride sublime. Only Iodine dissolves in carbon tetra chloride.

How will you seperate the three components? Sequence of steps will be

a) By sublimation addition of CCl4

b) Addition of CCl4 , filtration, sublimation

c) Sublimation, addition of H2O, filtration.

d) evaporation, distillation, crystalization

Answer 1

Answer is C
plzz.... make me a brainlist

Answer 2

We first analyse the question according to the information given in the question.

Iodine and Aluminium Chloride Sublime hence we cannot begin by separating them by distillation.

Iodine dissolves in Carbon tetra Chloride hence we can begin by dissolving the mixture in Carbon tetra Chloride to eliminate Iodine.

We then filter to obtain the mixture of Aluminium Chloride and sand.

Since only Aluminium chloride sublimes we separate the mixture by sublimation.

The separation steps are thus as follows :

1) Addition of CCl4

2) Filtration

3) Sublimation

The correct answer is thus B.
