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.
