| (i) The property used to separate the mixture is solubility of different components in different solvents. |
| (ii) Sulphur is soluble in carbon disulphide, salt in water and coal is insoluble in both. |
| (iii) X is water and Y is carbon disulphide. |
A) (i) and (ii) only
B) (ii) and (iii) only
C) (i) and (iii) only
D) All are correct.
Correct Answer: D
Solution :
Common salt is soluble in 'X' (i.e., water) while sulphur is soluble in 'Y' (i.e., carbon disulphide), both the solutes will be recovered from the filtrate by evaporation. But, coal is insoluble in both. It will be left behind as residue.
