Systematic name trisodium hydrogendicarbonate
Sodium sesquicarbonate is a double salt of sodium bicarbonate and sodium carbonate, it has a needle-like crystal structure.
The dihydrate is Na3H(CO3)2·2H2O, occurs in nature as the evaporite mineral trona.
Sodium sesquicarbonate can be used in following fields:
1.Bath salts, swimming pools and as an alkalinity source for water treatment.
2. used in the archaeological :conservation of objects made of copper and copper alloys that have been corroded by salt water. Treatment with sodium sesquicarbonate removes copper chlorides from the corroded layer; if these were not removed the object would continue to corrode ("copper disease") while exposed to air.
3. used as a precipitating water softener, it can combine with hard water minerals to form an insoluble precipitate, removing these hardness minerals from the water.
