Abstract This paper designed experiment device for the reaction of N2 and O2 under high voltage discharge. Used oxygen sensor and pressure sensor to measure oxygen concentration after discharge, and the decrease in oxygen concentration after stopping discharge indicated that NO was produced during the reaction. Then injected purple litmus solution into the reaction system, simulating the reaction of NO2 and water in rain, reddish brown became lighter, purple litmus solution turned red, and the value of oxygen sensor and pressure sensor decreased further, which explained that acidic substance and NO were produced.
