Answer 1

 (i) Firstly the mixture will be heated. As camphor is sublimable, it will vapourize and so it can be separated through sublimation. (ii) To separate mixture of common salt and soil, we will dissolve them in water. As salt is soluble in water, and soil is not soluble in water, soil can be separated through filtration. (iii) At the end we get salt solution. Salt can be separated from water by evaporation
OR
Camphor + Common salt + soil
1 Sublimation
Camphor Common salt + soil sublimes lAdd water
Salt dissolves filter soil as residue

Answer 2

you can separate camphor common salt and soil by using sublimation technique also
