Reactions of sulfur with other elements:
- Oxygen: Sulfur reacts with oxygen and form sulfur dioxide gas.
- Halogens: Sulfur can react with halogens, such as chlorine and fluorine, to form sulfur halides.
- Metals: Sulfur can react with many metals to form metal sulfides.
Reaction of sulfur with oxygen:
Sulfur reacts with oxygen and form sulfur dioxide:
Balanced equation for the reaction of sulfur with oxygen
S (s) + O2 (g) → SO2 (g)
Reaction of sulfur with hydrogen:
Sulfur reacts with hydrogen to form hydrogen sulfide:
Balanced equation for the reaction of sulfur with hydrogen
S (s) + H2 (g) → H2S (g)
Reaction of sulfur with chlorine:
Sulfur reacts with chlorine to form sulfur dichloride:
Balanced equation for the reaction of sulfur with chlorine
S (s) + Cl2 (g) → SCl2 (g)
Reaction of sulfur with fluorine:
Sulfur reacts with fluorine to form sulfur hexafluoride:
Balanced equation for the reaction of sulfur with fluorine
S (s) + 3F2 (g) → SF6 (g)
Reaction of sulfur with nitrogen:
Sulfur reacts with nitrogen to form sulfur nitride:
Balanced equation for the reaction of sulfur with nitrogen
S (s) + 2N2 (g) → S3N2 (s)
Reaction of sulfur with metals:
Sulfur reacts with many metals to form sulfides. The reaction can be represented by the general equation:
S (s) + M (s) → MS (s)
where M is the metal.

What does sulfur smell like?
Sulfur has a distinctive smell that is often described as being similar to rotten eggs or a skunk’s spray. This odor is caused by the presence of hydrogen sulfide gas, which is a byproduct of many sulfur-containing compounds. Sulfur is sometimes used in industrial applications to detect gas leaks or to give natural gas a distinctive scent so that leaks can be noticed more quickly, despite the fact that its smell is unpleasant.
Sulfur trioxide formula:
Sulfur trioxide is a chemical compound with the formula SO3. It is a white crystalline solid that is highly reactive and is often used as a catalyst or in the production of other chemicals, such as sulfuric acid. When SO3 is exposed to moisture, it can react violently to form sulfuric acid. Acid rain is also significantly influenced by sulfur trioxide.
Sulfur soap is a type of soap that contains sulfur as one of its main ingredients. It is often used to treat various skin conditions, such as acne, rosacea, and eczema, as sulfur has antimicrobial and anti-inflammatory properties.
Sulfur hexafluoride (SF6) is a colorless, odorless, non-toxic, and non-flammable gas. SF6 is considered a greenhouse gas and has a global warming potential that is much higher than other gases, which has led to efforts to reduce its use and find alternative insulating materials.
