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, so option A is correct. It releases carbon dioxide when heated or when it reacts with an acid, which helps baked products rise and also explains some antacid use. Sodium chloride, calcium carbonate and calcium hydroxide are different compounds.
