Baking soda

Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda or bicarbonate of soda (or simply "bicarb", especially in the UK), or salaratus, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO−3). Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder.

It has a slightly salty, alkaline taste resembling that of sodium carbonate ("washing soda").
The natural mineral form is nahcolite, although it is more commonly found as a component of the mineral trona.
