What does NaHCO3 stand for?

What does NaHCO3 stand for?

• A. Nitrous Hydrogen Carbonate
• B. Sodium Carbonate
• C. Sodium Hydrogen Carbonate
• D. Sodium Bicarbonate

Answer: (D)

NaHCO3 is sodium bicarbonate, a salt formed from a sodium ion and the bicarbonate (hydrogen carbonate) ion. The HCO3− group is the conjugate base of carbonic acid, so together with sodium it creates a buffering compound that helps manage acid–base balance. In medical and prehospital contexts, the common name used is sodium bicarbonate, even though it can also be called sodium hydrogen carbonate in more formal chemical naming. The carbonate form, Na2CO3, would lack the hydrogen on the carbonate ion, so it’s a different compound.
