The chemical formula for table salt is NaCl.

NaCl, the main component of table salt, is an ionic compound. Pure sodium chloride crystals are colorless and transparent cubic crystals, due to the presence of impurities make the general case of sodium chloride is white cubic crystals or fine crystal powder.

Crystal structure: the crystal cell is face-centered cubic structure, each cell contains 4 sodium ions and 4 chloride ions.

Uses of table salt

1, can be reacted with silver nitrate to get silver chloride precipitate.

2, solid table salt can be heated with concentrated sulfuric acid*** to get hydrogen chloride gas.

3, Electrolysis of sodium chloride solution can get chlorine gas, hydrogen gas and sodium hydroxide.

4, Electrolysis of molten sodium chloride can get monosodium and chlorine gas.
