What is the common name for the compound with formula NaHCO3?

This compound’s everyday name is baking soda. NaHCO3 identifies it chemically as sodium bicarbonate, but in cooking and on store shelves it’s known as baking soda. In baking, it acts as a leavening agent—when it reacts with acids or is heated, it releases carbon dioxide, helping dough rise. The label sodium bicarbonate is the formal chemical name, not the common name the question asks for. The misspelled Sodium Bcarbonate isn’t a real name for this compound, and water is a completely different substance with the formula H2O.
