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.
