When salt is mixed with water does it give off gas?

Answer 1

If we talk about table salt, it might produce small gas (air) bubbles by dissolving it in water. These small air bubbles were incorporated into the crystal structure at the crystallizing of the salt out of water and they are deliberated again by dissolution. There are other kind of salts which produce different kind of gases by dissolution but those gases are products of a chemical reaction between the salt and water.

Answer 2

Salts can be vaporised. For example common salt sodium chloride can be vaporised (boiling point 1413 °C, 1686 K, 2575 °F). In the vapour monomeric and dimeric molecules have been found. The bonding in these is still essentially ionic.

Many salts actually decompose for example NH4CL vapourises to form molecular NH3 and HCl.

Answer 3

In pure water no. It merely dissolves in water. Another chemical or external force would be required.

Answer 4

Not under "normal" circumstances

since the boiling point of salt is about 2500 degrees F (and your stove usually only goes up to 600).

Answer 5

No, mixing salt with water does not generate gas. The process of dissolving salt in water does not involve a chemical reaction that results in the release of gas.
