Please help give information about the properties of sodium sulfate, etc

Physical and chemical properties: appearance and properties: white, odorless, bitter crystals or powders, hygroscopic. Melting point ( ) 884 Relative density (water = 1):

Solubility: Insoluble in ethanol, soluble in water, soluble in glycerol.

Alias: miscanthus salt.

Uses: used in water glass, glass, enamel, pulp, refrigeration mixture, detergent, desiccant, dye diluent, analytical chemical reagents, pharmaceuticals, etc.

Chemical equation: Ca(OH)2+Na2SO4====CaSO4(slightly soluble)+2NaOH

bacl2+na2so4=baso4↓+2nacl2na2so3+o2=2na2so4

nahso4+naoh===na2so4+h20

Physical properties: white powder, soluble in water.

Chemical properties: Its aqueous solution, completely ionized into sodium ions and sulfate ions, can conduct electricity, and can metathesis with a salt solution containing barium ions to generate a precipitate insoluble in dilute acid. Sodium salts are all soluble salts, most of the sulfates are soluble, silver sulfates are slightly soluble, and other common sulfates are soluble.

Therefore, sodium sulfate is not easy to metadecompose reaction, and sodium sulfate is generally mentioned in the exam, which will involve barium sulfate precipitation.

Note that ferrous sulfate can be prepared by the reaction of iron and copper sulfate, but sodium sulfate cannot be prepared by the reaction of sodium metal and other metal sulfates. When examining, it may be mentioned:

Appearance and properties: white, odorless, bitter crystals or powders, hygroscopic.

pH: Melting Point( )884

Relative density (water = 1):

Solubility: Insoluble in ethanol, soluble in water, soluble in glycerol.

Main uses: used in water glass, glass, enamel, pulp, refrigeration mixture, detergent, desiccant, dye diluent, analytical chemical reagents, pharmaceuticals, etc.

The crystallization of sodium sulfate and water is commonly known as miscanthus nitrate, and the sulfur in sodium sulfate is +6 valence.

Sodium sulfate can be formed by the reaction of sodium sulfite plus hydrogen peroxide to produce sulfur dioxide at the same time

Sodium sulfite + hydrogen peroxide = sodium sulfate + sulfur dioxide

There are other properties that are not easy to play here, you can check on google, and it is easy to find o(o
