Sodium Chloride → Sodium Carbonate

Participants

Reaction Steps

Primary Treatment: The recrystallized NaCl prepared in step 1 was again dissolved in the de-ionized water and to it was added calculated amount of barium carbonate in equal molar ratio slight excess than the amount of sulphates present (which was first tested). Barium carbonate reacts with sodium sulphate to form Na2CO3 and BaSO4. BaSO4 is water insoluble and hence precipitated out. The mixture was heated after the addition of barium carbonate for 15 minutes at 80° C.
