Physical Method:
To separate the iron filings and sulphur powder from the mixture, a physical method called magnetic separation can be used. This method takes advantage of the magnetic properties of iron.
1. Magnetic Separation:
- Place a magnet near the china dish containing the mixture.
- The iron filings, being magnetic, will be attracted to the magnet and stick to it.
- Slowly move the magnet around the dish to collect all the iron filings.
- Remove the magnet from the dish, leaving only the sulphur powder behind.
Explanation:
The physical method of magnetic separation is suitable for separating mixtures that contain components with different magnetic properties. In this case, the iron filings have magnetic properties, while sulphur powder does not. By using a magnet, the iron filings can be easily separated from the mixture.
When the magnet is brought close to the china dish, the magnetic force exerted by the magnet attracts the iron filings towards it. As a result, the iron filings stick to the magnet and can be effectively separated from the mixture. On the other hand, the sulphur powder remains unaffected by the magnet and stays in the dish.
This method is based on the principle that substances with magnetic properties can be separated from those without magnetic properties by utilizing magnetic forces. It is a simple and efficient way to separate iron filings from a mixture.
Conclusion:
In conclusion, the physical method of magnetic separation can be used to separate iron filings and sulphur powder from their mixture. By using a magnet, the iron filings can be attracted and separated, while the sulphur powder remains behind in the china dish. This method is a practical and effective way to separate components with different magnetic properties.
