Question

Your chemistry teacher has provided you with a mixture containing sand iron filling ammonium chloride and sodium chloride describe the procedure you would used to separate these constituents from the mixture

Answer 1

to separate the mixture of the following substance we need to do---
1. at first by the help of a magnet separate the iron filling from the mixture.
2.by the help of the property of the ammonium chloride to sublime the ammonia chloride will get separated.
3.then the mixture of podium chloride and sand remains, so the add some amount of water to the mixture.
4.and by the help of ultra filtering paper filter the solution as the sodium chloride is dissolved in the water but the sand does not.
5.and then by the process of crystallisation obtain the crystal of the sodium chloride.

hence the four substance are separated. ......
