Analyse why sulphur cannot be used to prevent rusting.
✓
Answer
Sulfur cannot be used to prevent rusting because when sulfur is burned in the air, sulfur dioxide gas is formed. When sulfur dioxide gas is dissolved in water, sulfurous acid is formed. For rusting to happen, there must be water, and if we add Sulphur, it will hasten the process of rusting.
