## Description

Water Electrolysis Apparatus Electrolyte Tester Chemistry Experiment Teaching Apparatus, Chemistry Demonstration Water Electrolysis and Hydrogen and Oxygen Teaching Instrument.

## Features

- ✔ The water electrolysis experimenter allows students to understand the process of generating hydrogen and oxygen after water is energized. The instrument is composed of plastic container, electrode, gas nozzle and so on.
- ✔ Purpose-Demonstrate the electrolysis process of water and hydrogen and the process of oxygen production in middle school chemistry class.
- ✔ Structure-scale tube (scale value 1ml), alloy electrode, plastic base..
- ✔ Performance-Under the action of 12V-18V DC voltage, the oxygen-to-hydrogen ratio (10:20) produced in 3-5 minutes verifies that water molecules are composed of one oxygen atom and two hydrogen atoms..
- ✔ Note-In the experiment, 10% sulfuric acid or sodium hydroxide (salt) can be added to the water to increase the conductive effect.
