What is the main difference between baking soda and baking powder?
Answer and explanation
Correct answer: Baking powder contains baking soda along with an acidic component
The governing concept is the composition and acid-base reaction of baking agents. Baking soda is mainly sodium hydrogen carbonate, a single chemical compound that needs an external acid to release carbon dioxide efficiently. Baking powder is a mixture containing baking soda, one or more dry acidic substances, and commonly a starch-like filler. Moisture and heat allow the components to react and produce leavening gas. Hence option A is correct; the other statements confuse composition or falsely claim identity.
