Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate[10]), commonly known as baking soda or bicarbonate of soda (or simply “ bicarb ” especially in the UK) is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3−).

It has a role as an antacid and a food anticaking agent. It contains a hydrogencarbonate. Sodium bicarbonate is a white, crystalline powder that is commonly used as a pH buffering agent, an electrolyte replenisher, systemic alkalizer and in topical cleansing solutions. View More...

Sodium carbonate (also known as washing soda, soda ash, sal soda, and soda crystals) is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, odourless, water-soluble salts that yield alkaline solutions in water.

2018年5月11日 · In the first method, carbon dioxide gas is passed through an aqueous solution of sodium carbonate (Na 2 CO 3): Since the bicarbonate is less soluble than the carbonate, it precipitates out of solution and can be removed by filtration. Sodium bicarbonate is also obtained as a byproduct of the Solvay process.

2025年3月21日 · sodium bicarbonate (NaHCO3), white crystalline or powdery solid that is a source of carbon dioxide and so is used as an ingredient in baking powders, in effervescent salts and beverages, and as a constituent of dry-chemical fire extinguishers. Its slight alkalinity makes it useful in treating gastric or urinary hyperacidity and acidosis.

2017年1月27日 · Gets facts about sodium bicarbonate or baking soda, including its chemical formula, alternate names, molecular weight, melting point, and density.

2024年4月22日 · What is sodium bicarbonate? Sodium bicarbonate, formula NaHCO 3, is a white crystalline solid soluble in water. It is also known by other synonyms: sodium hydrogen carbonate or bicarbonate of soda. It has a slightly alkaline taste similar to sodium carbonate, although less strong and more salty.
