Grape juice indicator. Purple grape juice changes its color depending on the pH of the solution. Here grape juice was added to two household solutions: vinegar (mostly diluted acetic acid, CH3COOH) and baking soda solution (sodium bicarbonate, NaHCO3). Vinegar is acidic and turns grape juice pink/red. Baking soda is alkaline and turns grape juice dark green.
