What is the chemical name of baking soda?
Answer and explanation
Correct answer: Sodium hydrogen carbonate
Baking soda is the common name for sodium hydrogen carbonate, whose formula is NaHCO₃. It is a mild basic salt and reacts with acids to release carbon dioxide, which explains its use in baking and some antacid preparations. Hence option A is correct. Sodium carbonate decahydrate is washing soda, calcium sulphate is a different salt, and sodium chloride is common table salt, so none of those alternatives identifies baking soda.
