What is the chemical name of baking soda?

Answer and explanation

Correct answer: Sodium hydrogen carbonate

The governing concept is the identification of common salts by their chemical names and formulae. Baking soda is sodium hydrogen carbonate, NaHCO₃. When it reacts with an acid, it produces carbon dioxide, water, and another salt; for example, NaHCO₃ + HCl → NaCl + H₂O + CO₂. Therefore option A is correct. Sodium chloride is common salt, sodium carbonate decahydrate is washing soda, and calcium carbonate is found in limestone and chalk.
