Be careful not to spill the solution on the skin when pouring the solution during the experiment, so as not to damage the skin2. Note that the container and carbon rod should be thoroughly cleaned after the experiment, and put in a dry place after drying.3. Do not place the instrument in a place with corrosive gas.Find answers in product info, Q&As, reviews

• 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.
• 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.
• Pour the crystal sodium chloride into the container, turn on the power, find that the light-emitting diode is not bright, pour the crystal electrolyte into a beaker and heat or pour water to melt it, you will find that the solution starts to conduct electricity, which proves that the electrolyte is free to be charged Moving ions.
