• ★This instrument is suitable for the experiment of electrolyte solution in middle school chemistry teaching, understand the concept of strong electrolyte and weak electrolyte, and understand the essence of electrolyte solution conductivity.
• ★Pour the experimental sodium hydroxide solution, sodium chloride solution, hydrochloric acid solution, 40% acetic acid, and 20% ammonia water into the container equipped with the instrument, connect it to the socket of the instrument with a wire, then turn on the power and turn on the switch , Observe the light-emitting condition of the light-emitting diode to determine the strength of the measured solution.
• ★Pour the crystal sodium oxide into the container, turn on the power, find that the light-emitting diode is not bright, pour the crystal electrolyte into a beaker or pour water to melt it, you will find that the solution starts to conduct electricity, which proves that the electrolyte is charged and can move freely Of ions.
• ★If the solution is a strong electrolyte solution, the light-emitting diodes are all on; if the solution is a weak electrolyte solution, the light-emitting diodes will light up one or two; if the solution is a non-electrolyte solution, the light-emitting diodes will not light up.
• ★Good for school teaching tool, learning display, and collectibles, also will be a great addition to your lab supplies.
