Question

In a mixture of iron fillings and sulphur what is the colour of sulphur particles and how can you separate iron fillings

Answer 1

Demonstrate that iron can be separated from the mixture by physical means. Do this by wrapping the end of a small bar magnet in a paper tissue or cling film, and dipping it into a teaspoon-sized heap of the mixture on a watch glass. Theiron will be attracted, but the sulfur remains on the watch glass.
