Soda ash
Sodium carbonate in scientific name, soda soda in common name, stone alkali, washing alkali, chemical formula Na2CO3, belonging to In salts, sodium carbonate containing ten crystal water is colorless crystal, crystal water is unstable, easy to weathering,
It becomes a white powder Na2CO3, a strong electrolyte, with salt connectivity and thermal stability, easily soluble water, its aqueous solution is basic.
Light / Dense Soda Ash
Sodium Carbonate (Na2CO3), commonly known as Soda Ash, may well have been the third "industrial chemical" used by man; perhaps employed sometime after salt (NaCl) and lime (CaO).
