Describe the various steps involved in the separation of iodine, iron filings and salt from a mixture.
The following steps are involved in the separation of iron filings, chalk powder, and common salt:
- A magnet is moved over the mixture of iodine, iron fillings, and salt. Due to the magnetic property of iron, iron filings are separated by the magnet.
- The mixture now contains iodine and salt. Iodine sublimes on heating but salt does not. Hence, on heating the mixture, the vapours of iodine are obtained.
- Vapours of iodine are condensed in a cold apparatus. Salt remains behind as residue.
