This consistency defines a substance; its chemical identity is immutable. This creates a crystalline structure where the ratio is exact: one sodium atom for every chlorine atom.
Rock Salt: Substance Versus Mixture
This familiar white crystal, essential for flavor and preservation, prompts a fundamental question about its very nature: is salt a substance or mixture ? The Chemical Definition of a Pure Substance To resolve this, we must look to the scientific classification of matter. Water (H₂O) is a classic compound, always consisting of two hydrogen atoms for every oxygen atom, whether in a glass or an ocean.
Therefore, a typical salt shaker holds a mixture: the base substance of sodium chloride combined with other discrete ingredients that retain their individual properties within the blend. Because these components can be mechanically separated without altering their chemical structure, the final product on your counter fits the definition of a mixture, even if the dominant element is a pure substance.

Because this composition is fixed, pure sodium chloride qualifies as a substance, not a mixture. These additional elements are not chemically bonded to the sodium chloride; they are simply mixed in.
