HI, I'm new around. My questions is: I have salty water which I perform electrolysis on using copper probes (cathode and anode). One of the copper probes nothing happens to as far as I can see (can't remember which one it is) but the other starts to wear away and turn the water blue/green.
اقرأ أكثرCopper refining to an almost pure state done by electrolysis is an excellent example of the process. Blister copper is considered to be a highly pure form of copper - around 99%. However, in today's market, this level of purity is still not enough; as a result, the blister copper is purified further using an electrolysis process known as ...
اقرأ أكثرThe sintered copper oxide pellets were electrolyzed for 20 h with different voltages in a 50 mL electrolysis bath at 353 K, respectively. The current value is found to sharply increase with increasing the applied voltage from 2.0 to 2.4 V, which is generally attributed to the enhancement of driving force for the electrode reaction.
