What is the chemical formula of sodium bicarbonate?

The chemical formula of sodium bicarbonate is NaHCO? .

As an inorganic salt, sodium bicarbonate is a white crystalline powder, odorless, alkaline and soluble in water. Slowly decompose in humid air or hot air to produce carbon dioxide, completely decompose when heated to 270℃, and strongly decompose in acid to produce carbon dioxide.

It is stable at room temperature, easy to decompose when heated, rapidly decomposes above 50℃, completely loses carbon dioxide at 270℃, remains unchanged in dry air, slowly decomposes in humid air, and can react with acid and alkali.

Extended data:

The main components of scale are calcium carbonate, magnesium carbonate and magnesium hydroxide. These components will not react with alkali, only acid can remove them, so baking soda can't be used to remove scale.

The composition of rust is iron oxide, which does not react with alkali, so baking soda cannot remove rust. Although acetic acid can slowly dissolve rust, the concentration of acetic acid in white vinegar is only 3%-5%, which basically has no rust removal effect.
