Chemical formula NaHCO₃

NaHCO₃ is the chemical formula for sodium bicarbonate, commonly known as baking soda. It consists of three types of atoms: sodium (Na), hydrogen (H), carbon (C), and oxygen (O). Specifically, one sodium atom is bonded with a bicarbonate group (HCO₃), which includes one carbon atom connected to three oxygen atoms and one hydrogen atom. Sodium bicarbonate is a mild base used in baking to help dough rise, as a cleaning agent, and for medical purposes like treating indigestion. Its structure allows it to react with acids and release carbon dioxide gas, causing bubbling or foaming.
