Conversion of Sodium Bicarbonate into Sodium Carbonate Cog.png
Sodium carbonate on left and bicarbonate on right, both in oversaturated solutions.
After vs Before the conversion. Sodium carbonate on left and bicarbonate on right. Notice how carbonate is more grainy and bicarbonate more loose/fluffy
  1. Weigh your sodium bicarbonate, and put it onto a non-aluminum pan or oven-safe dish.
  2. Place in the oven at 400ºF (205ºC) for one hour to one hour and a half to release CO2 and water. Alternatively you can put in a stainless steel (dont use any other material!) pot on the stovetop, 20mins should be enough. Be careful because the powder will be VERY hot, leave it to cool down for a while.
  3. The resulting material should have lost around 20% of the original weight. It will be of a slightly less powdery consistency, closer to sugar than flour. If it didnt lose a third of the original weigh, leave it for longer in the oven
    • sodium carbonate feels a bit looser and grainier than bicarbonate, and in an oversaturated solution, sodium bicarbonate will remain powdery while sodium carbonate tends to rock up.

This can also be done on a stove top/oven ring in a pot and take around 10 minutes to completely dehydrate
