Sodium chloride, table salt, a simple structure with one salt molecule for every two water molecules, was previously the only known hydrate.

This salt crystal is both exotic and common: It’s actually table salt — also known as sodium chloride, with the chemical formula NaCl — but bound up with water molecules to form a hydrate ...

After the study experiment, the researchers discovered two new hydrates — one utilizing two salt molecules for every 17 water molecules, and another with one salt molecule for every 13 molecules.

Each salt molecule can hold a certain number of water molecules within its structure. To instigate the chemical reaction, the researchers dehydrate the salt with heat, so it expels water vapor as ...

Although his eponymous salt is an inorganic compound, he is mainly known as a pioneer in organic chemistry; many biographical accounts of Chevreul, who lived to age 102, do not even mention the salt.

Researchers have developed a sponge-like material with long, microscopic air pockets that uses sunlight and a simple plastic ...

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. That’s why ...
