When you use 12V to electrolyze clear water (by myself :) and use copper as the electrode, the copper in the anode will be corroded and the water will turn into a green cloudy liquid clear, and the speed of change is relatively slow. When using graphite, it will also turn light brown. The speed of change is very slow and takes around 3 days. The principle is unknown. The graphite powder remaining after polishing the graphite surface may be dispersed in the liquid. there may be impurities. Using a 220v power supply (I used AC) will cause violent reactions and produce severe fires. This is more dangerous and is not recommended. If it is direct current (I haven't tried it), it is recommended to increase the distance between the two. the two poles (it is recommended to be greater than 50 cm), and separate the gas generated at the two poles. BornDo not mix when collecting. Use a well-ventilated, open area and be prepared to light the fire. electrodes with high melting points and difficult to catch fire, such as copper, and add protection switches and protection resistors to the circuit.
Which electrolyte solution is used to quickly produce gas in the water electrolysis experiment?
Using the electrolysis method
The The process of using electricity to break down compounds is called the process of electrolysis. Water (H2O) is electrolyzed to produce electrolyzed water. When electric current passes through water (H20), hydrogen is formed at the cathode and oxygen is formed at the anode. towards the cathode and the minerals dissolved in the water. Positively charged ions such as calcium, magnesium, potassium and sodium form at the cathode, which is the alkaline water we drink, while ionsNegatively charged cells form at the anode.
Add tap water The chlorine in the electrolyzed acidic water is also discharged into the acidic water at the anode. Because electrolytic acid water has a pre-filtration system and silver-loaded antibacterial activated carbon, there is. almost no trace of chlorine in acidic water.
The principle of electrolysis seems simple, but it is not easy to generate electrolyzed water quickly and safely. After continuous improvement, manufacturers began to use safe and stable metal titanium. as electrodes
No sodium chloride can be added to electrolyzed water, so many categories of substances can be added 1. Oxyacids. Such as sulfuric acid, nitric acid, acetic acid, etc. 2. Strong alkali, sodium hydroxide, barium hydroxide, etc. 3. Oxylated salts of active metals, such as sodium sulfate, s carbonateodium, etc. The electrolysis of these three substances is equivalent to the electrolysis of water. As for the number of minutes, I have never tried that, I hope it helps, and I wish you academic progress
