Sodium salts are salts that have sodium ions and acid radical ions chemically combined, such as sodium chloride, a common table salt. The sodium ion is +1 valence, most of the sodium salt is soluble in water. There are also a small number of sodium salts insoluble in water or slightly soluble in water, such as sodium titanate Na2Ti3O7, sodium bismuth NaBiO3, sodium urethane Na2C5H2N4O3 and so on.

1, sodium chloride: colorless cubic crystals or white crystals. Soluble in water, glycerin, slightly soluble in ethanol, liquid ammonia. Insoluble in concentrated hydrochloric acid. Slightly deliquescent in air. Used in the manufacture of soda ash and caustic soda and other chemical products, ore smelting. Used in food industry and fishery for salt pickling, also used as raw material for seasoning and refined table salt.

2, sodium sulfate: sodium sulfate, inorganic compounds, sodium sulfate decahydrate, also known as manganese, white, odorless, bitter crystals or powder, hygroscopic. Anhydrous sodium sulfate chemical formula for Na2SO4, sodium sulfate decahydrate chemical formula for Na2SO4-10H2O.

3, sodium thiosulfate: sodium thiosulfate, chemical formula: Na2S2O3, monoclinic crystalline system, white crystalline powder, specific gravity of 1.667, easily soluble in water, insoluble in alcohols, heated in the air is oxidized and decomposed into sodium sulfate and sulfur dioxide. Often as sodium thiosulfate pentahydrate, relative molecular weight 248.18. Relative molecular weight 248.18, solution is colorless solution.
