Baking soda:
Stable at room temperature and easy to decompose when heated. It decomposes rapidly above 50℃, completely loses carbon dioxide at 270℃, remains unchanged in dry air, and slowly decomposes in humid air. It can react with acids and bases. React with acid to generate corresponding salt, water and carbon dioxide, and react with alkali to generate corresponding carbonate and water. In addition, it can also react with some salts and double hydrolyze with aluminum chloride and aluminum chlorate to produce aluminum hydroxide, sodium salt and carbon dioxide.
