Electrolytic water experiment I want to do the electrolytic water test! But I don't know how many volts the power supply needs to be qualified! Is the ordinary 1.5V dry battery OK?

Ordinary 1.5V dry cell is absolutely impossible. At least 8-10 No. 5 dry cells need to be used in series to electrolyze water (that is, 12-15v, if the voltage is higher, the speed will be faster). I have done this experiment. It is better to add a small amount of NaCl to help conduct electricity, which can save the battery



What is the relationship between cathode and anode in electrolyzed water test=


The positive electrode gains electrons and the negative electrode loses electrons
The cathode gains electrons and the anode loses them
The positive pole is connected to the anode and the negative pole to the cathode
Memory: positive oxygen (loss of electrons due to anodic oxidation)
The anode and cathode are electrolysis, and the anode and cathode are batteries
