Which method should be used to separate Iron from Sulphur?
Dear Student,
There are four methods used in the separation of iron from sulphur are,
1. Basics
2. Washing
3. Magnetism
4. Carbon Disulfide
The Basics
-
The separation of sulfur and iron can only occur if the two compounds have not chemically reacted. It is thus important to note that if the mixture between the iron fillings and sulfur is heated, a chemical compound called iron sulfide is formed. To separate iron and sulfur that have not chemically reacted, two methods are magnetism and the use of carbon disulfide.
Washing
-
During the process of separating iron and sulfur, in case of an iron ore, the finely crashed iron ore is washed in a stream of water. During this period, the other particles other than iron are washed away while the iron material sinks. These materials are then dried and separated using a magnet, since iron is magnetic.
Magnetism
-
If it is a mixture of iron fillings and sulfur, a magnet is used to separate the Iron fillings from sulfur particles since the sulfur particles are not attracted by the magnet. To make sure the magnet picks all the pieces of iron fillings, you can stir the container using the magnetic bar, and the iron fillings will stick on the magnetic bar. Swirling the mixture with the magnet under the container is also another method that can be used, since the Iron filings will fall towards the place where the magnet is.
Carbon Disulfide
-
Whereas sulfur is insoluble in water, it dissolves when mixed with carbon disulfide. Because of this, carbon disulfide is used to separate iron from sulfur. The mixture of sulfur and iron is put in a carbon disulfide solution. After shaking well, the sulfur component dissolves in the carbon disulfide solution while iron does not. The new formed solution is then filtered and iron particles are left behind. To separate sulfur from carbon disulfide, the solvent is evaporated, which leaves a residue of pure sulfur.
