Question

33 baking soda reacts with the following ingredients: a eggs b buttermilk c powdered sugar d all the above

Explanation:

Baking soda (sodium bicarbonate) reacts with acidic substances. Buttermilk is acidic (contains lactic acid), so baking soda reacts with it. Eggs are mainly protein/fat/water and not acidic enough to react with baking soda, and powdered sugar is a carbohydrate with no acidic components to react with baking soda. So only buttermilk (option B) is correct? Wait, no—wait, actually, baking soda needs an acid to react (like in baking, it reacts with acidic ingredients to produce CO₂). Buttermilk is acidic (lactic acid), so baking soda reacts with buttermilk. Eggs: eggs have some components but not acidic enough for a reaction with baking soda. Powdered sugar is sucrose, no acid. So the correct option is B. Buttermilk is acidic, so baking soda (basic) reacts with it. Eggs and powdered sugar don't have the acidic component to react with baking soda. So the correct answer is B. Buttermilk.

Answer:

B. buttermilk
