Question

You are provided with a mixture of sand, iron and camphor. Describe the procedures you would use to separate these constituents from the mixture?

Answer 1

Answer:Place the mixture on a paper of petridish, move a bar magnet many times over the mixture. Iron filings get attached to the magnet and get separated. <br> (ii) Remove ammonium chloride from sand and sodium chloride by sublimation <br> The remaining mixture is transferred to China dish and subjected to sublimation. Ammonium chloride will get vaporised and change into vapours and on condensation will form

. Sand and sodium chloride will be left in China dish. <br> (iii) Remove sand from sodium chloride by filtration after dissolution <br> Dissolve the sand and sodium chloride in water. Sodium chloride will dissolve. Filter the solution. Sand will be left as residue and is separated. <br> (iv) Get sodium chloride by evaporation or crystallisation. In the filtrate sodium chloride is present. So, evaporate the filtrate to dryness to get sodium chloride back or use crystallisation.
