Caption: Three household solutions are tested for pH using a universal indicator paper. For baking soda (sodium bicarbonate), the test strip changes its colour to green, indicating an alkaline solution. For rubbing alcohol (isopropanol), the test strip colour is unchanged from yellow, indicating a neutral solution. For vinegar (dilute acetic acid), the test strip changes its colour to orange, indicating an acidic solution.
