If the unknown powder is indeed baking soda (sodium bicarbonate, NaHCO₃), the student can expect a fizzing or bubbling reaction when the powder is mixed with vinegar (acetic acid, CH₃COOH). This reaction occurs because vinegar is an acid that reacts with baking soda, producing carbon dioxide gas, water, and sodium acetate. The effervescence (bubbling) is due to the release of carbon dioxide gas, which is a clear indicator that the powder is likely baking soda.
