I have a discussion with my friend, that if you take sodium bicarbonate= NA2CO3, heat it up to 200c for 10 minutes, the result will be caliumcarbonate= K2CO3, somebody on this forum who can help us with the correct result.
Thanks.

If you take Sodium Carbonate (Na2CO3, Sodium bicarbonate is NaHCO3) and heat it to 200 degrees celsius, you'll end up with Sodium Carbonate at 200 degrees celsius (Calcium Carbonate is CaCO3, what you wrote is potassium carbonate).

Sodium Bicarbonate, NaHCO3, apparently decomposes around 70 degree celsius and this speeds up at 200 degree celsius to sodium carbonate, water and carbon dioxide.

That's the opinion of Dr. Wiki Pedia, Ph. D from what I can see at least.

How did the Soduim-Calcium exchange take place?? How did Calcium appear out of nowhere? And what happened to the Sodium?

The only thing I can remember about heating Na2CO3 is that if you reach really high temperature the compound dissociates into Na2O and CO2...

BTW "K2CO3= calcium carbonate" must be typo right?
