Indeed, sodium chloride — each molecule consists of one sodium atom and one chlorine atom — is often thought of first as an antifreeze, lowering the freezing temperature of water.

Show students that the positive area of a water molecule will be attracted to the negative chloride ion and that the negative area of a water molecule will be attracted to the positive sodium ion.

Researchers have synthesized a powerful new molecule to trap chloride salts. The technology has the potential to reduce its seepage into freshwater systems, which is a threat to drinkable water ...

The only previously known hydrate for sodium chloride was a simple structure with one salt molecule for every two water molecules.

close giant ionic latticeThe structure of ionic compounds formed from millions of oppositely charged ions in a 3 dimensional arrangement. structure with equal numbers of sodium and chloride ions.

Scientists found that three water molecules surrounding a single sodium ion can travel exceptionally fast on a sodium chloride molecule's surface.

The structure on the right has one sodium chloride molecule for every 13 water molecules, and is stable only at high pressure.

It's still the same molecule—sodium chloride—but table salt is ground, purified, and often has additives like iodine (in order to decrease the incidence of goiters) and anti-clumping agents.
