Sodium bicarbonate facts

Sodium bicarbonate is a white crystalline powder with a slightly salty, alkaline taste, sold as baking soda.
It is used as a leavening agent in baking, as an antacid, as a gentle cleaning powder, and in some dry chemical fire extinguishers.
When it is heated or mixed with an acid such as vinegar or buttermilk, it releases carbon dioxide gas, which makes batter rise.
