Uses

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.
