Iodized table salt is a mixture, not a pure substance. NaCl with no iodine is a pure substance. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose).

Also, what is table salt an example of?

Table salt is one of the most common household chemicals. Table salt is 97% to 99% sodium chloride, NaCl. Pure sodium chloride is an ionic crystal solid. However, other compounds are present in table salt, depending on its source or additives that may be included before packaging.

Similarly, what kind of molecule is table salt?

Table salt is an ionic compound, which breaks into its component ions or dissociates in water. These ions are Na+ and Cl-. The sodium and chlorine atoms are present in equal amounts (1:1 ratio), arranged to form a cubic crystal lattice. The molecular formula of table salt—sodium chloride—is NaCl.

Why is table salt a mixture?

A pure substance consists of a single element or compound. Iron is formed only of iron (Fe) atoms; table salt is formed only by sodium chloride (NaCl) molecules. A mixture, however, is made up of different compounds and/or elements. When salt is added to water to make saltwater, it becomes a mixture.
