(i) There will be no reaction. Carbon disulphide is a colourless liquid. Iron sulphide is an ionic compound while carbon disulphide is a nonpolar molecule. Iron sulphide is not soluble in carbon disulphide, and hence the carbon disulphide remains colourless.
(ii) When HCl is added to a mixture of iron filings and sulphur powder, then iron being more reactive than hydrogen will displace hydrogen from the acid, forming its salt instead. The sulphur powder will not react with HCl. Following is the reaction between Fe and HCl
Fe + 2HCl → FeCl2 + H2

Introduction to Carbon Disulphide
Carbon disulphide (CS2) is a colorless, flammable liquid commonly used as a solvent in laboratories. While it is effective for separating mixtures, it poses certain hazards that require specific precautions.
Flammability Concerns
- Highly Flammable: Carbon disulphide is highly flammable, meaning it can easily ignite when exposed to open flames or sparks.
- Vapor Risks: The vapors from carbon disulphide can also catch fire even at a distance from the liquid source, making it critical to keep it away from any ignition sources.
Why Keep Away from Flames?
- Fire Hazard: If CS2 comes into contact with a flame, it can lead to dangerous flashbacks and potential explosions.
- Safety Measures: Always conduct experiments involving carbon disulphide in a well-ventilated area and away from any heat sources to minimize the risk of fire.
Other Precautions
- Avoid Water: While water is not a direct concern in terms of flammability, mixing CS2 with water can lead to the formation of hazardous by-products.
- Air Exposure: Although air exposure is not as critical as flames, CS2 should still be handled in a way to minimize exposure to air to prevent degradation.
Conclusion
In summary, when working with carbon disulphide, the primary precaution is to keep it away from flames due to its flammability. Always prioritize safety by following proper laboratory protocols to handle this solvent carefully.
