In the experiment we added 20 drops of household solutions (from left-to-right: lemon juice, vinegar, Sprite, laundry detergent, antacid) to red cabbage juice. Under different pH conditions, red cabbage juice (naturally purple as can be seen in the far right test tube) changes from bright read at a low pH to a bright green at a high pH.
