Observing tube x 2; electrolytic cell X1, rubber stopper × 2 and carbon bar crevice x 2 This device is used for the electrolysis of water and the junior high school chemical class to demonstrate hydrogen and oxygen.
One water molecule is verified that two hydrogen atoms and one oxygen atom are verified, and hydrogen and oxygen are 10 ml: 12 V.1a under the action of 1a DC current, in 3-5 minutes 20 ml of electrolyzed water was generated.

Instructions:
1. Please prepare 200m clean water (preferably distilled water) in order to enhance conductivity. Add 10% sulfuric acid or sodium hydroxide to the water.
Put the prepared solution into the airtight chamber through the funnel. When adding the solution, raise the funnel and gently squeeze the glass ball to discharge the air in the tube. The solution can be added quickly.
Make the water levels in the two observation tubes rise to the top of the tubes respectively.

2. Connect the positive and negative wires of the power supply to the bottom electrode, turn on the power supply, and immediately see that there are bubbles in the two observation tubes. After about 3-5 minutes, it can be observed that the gas collected in the glass tube connected to the positive electrode is about It is one-half of the volume of gas collected in the glass tube connected to the negative electrode.
