Is salt an element, a compound, or a mixture?
Short answer
Pure salt, sodium chloride, is a compound: two elements, sodium and chlorine, chemically bonded in a fixed 1:1 ratio. Table salt you buy is technically a mixture, because it may contain small amounts of iodine compounds and anti-caking agents. Salt water is also a mixture: salt dissolved in water.
From elements to a mixture
- 1Sodium (Na): reactive metal
- 2+ Chlorine (Cl): toxic gas
- 3= Sodium chloride: a compound
- 4+ iodine, anti-caking agent = table salt (mixture)
Element vs compound vs mixture
- Element: one kind of atom, such as sodium (Na) or chlorine (Cl).
- Compound: two or more elements chemically bonded in a fixed ratio, such as NaCl.
- Mixture: substances combined physically, which can be separated without chemical reactions.
Salt, step by step
| Sodium | Element: a soft, reactive metal |
|---|---|
| Chlorine | Element: a toxic green gas |
| Sodium chloride | Compound: stable, edible crystals |
| Iodized table salt | Mixture: NaCl plus potassium iodide and anti-caking agent |
| Salt water | Mixture (solution): NaCl dissolved in water |
That two dangerous elements form a harmless compound is a classic example of how chemical bonding changes properties.
