Sodium Hydrogen Carbonate
Sodium Bicarbonate
Sodium bicarbonate or sodium hydrogen carbonate, also commonly known as bicarbonate of soda, is the chemical compound with the formula NaHCO3. Sodium bicarbonate is an odourless, white solid that is crystalline but often appears as a fine powder. It is slightly alkaline similar to that of washing soda (sodium carbonate). It is a component of the mineral natron and is found dissolved in many mineral springs. The natural mineral form is known as nahcolite. It is also produced artificially.
Sodium bicarbonate is used as a cleaner, pH adjuster for swimming pools and spas, laboratory reagent, pesticide, odour remover
