How does baking soda help food rise when it reacts with an acid?
Answer and explanation
Correct answer: By producing carbon dioxide bubbles
Baking soda is sodium hydrogen carbonate, NaHCO₃. When it reacts with an acid, the reaction produces carbon dioxide gas, along with a salt and water; for example, an acid plus hydrogencarbonate releases CO₂. The gas gets trapped as small bubbles in the batter or dough, making it expand, rise, and become porous. Thus option A is correct; the other choices describe substances or changes not produced in this reaction.
