Use toothpicks or paint brushes to make designs on the cornstarch with the vinegar (turns red cabbage cornstarch mix pink) and baking soda solution (turns red cabbage cornstarch mix blue.) The study of fermentation is called zymology . The unknown will react with each test solution the same way that baking powder does because the unknown is baking powder. Mixing baking soda and vinegar will create a chemical reaction because one is an acid and the other a base. Baking soda is pure sodium bicarbonate, which reacts with acidic solutions such as vinegar to produce carbon dioxide bubbles. These studies are difficult to compare because of differences in study design: healthy subjects versus those with insulin resistance or diabetes; when and how much vinegar was taken; the carbohydrate content of meals; and a diet that was high versus low glycemic index. cornstarch outside the UK) and water .
