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, with the formula NaHCO₃. It is a mild basic salt and reacts with acids to release carbon dioxide, for example NaHCO₃ + HCl → NaCl + H₂O + CO₂. Thus option A is correct. Sodium chloride is common salt, sodium carbonate decahydrate is washing soda, and calcium carbonate is found in substances such as limestone and chalk.
