There are three theoretically possible chemical reactions that could occur during the thermal decomposition of baking
soda.
1)
sodium bicarbonate (s) → sodium hydroxide (s) + carbon dioxide (g)
2)
sodium bicarbonate (s) → sodium oxide (s) + carbon dioxide (g) + water (g)
3)
sodium bicarbonate (s)→ sodium carbonate (s) + carbon dioxide (g) + water (g)
