Notice: 1. Keep the test tube dry before heating, and place it on the flame of the alcohol lamp to preheat so as to prevent the test tube from cracking. 2. A mass of cotton must be stuffed into the glass tube inside the test tube in order to prevent particulate matter from entering the tube after being heated by potassium permanganate. 3. The outlet of the test tube must be slightly inclined downward to prevent the condensation of water vapor flowing back to the high temperature and breaking the test tube. 4. You are supposed to move the gas-guide tube out of the water and then extinguish the alcohol lamp to prevent the water from flowing backwards in the sink and bursting the test tube.
