wazani said:the product of the reaction is chlorine at anode and hydrogen gas at cathode and sodium hydroxide solution .the yellowish color produced because some of yellowish chlorine dissolved in the alkali solution .
The cause of the color change observed in the video is very different from the situation you are describing. In the case of the video, the color change is easily explained by the oxidation of the iron (stainless steel spoons) into Fe+2 (aq) ions in solution. But you claim that you are not using iron, you only use copper and carbon, and the copper is not even touching the solution (If the copper was being oxidized to Cu+2 and put into solution, it would turn blue by the way).asamaid1 said:Hi,
see this you tube link

the same thing happens when i do this, but i used carbon for electrodes, and conecting wires do not touch the solution. thaks
Hi,mrjeffy321 said:How much of that powder do you get? Enough to do a couple of experiments on it? You could try filtering it out and drying it. Then see what acids will dissolve it, and / or what happens when you heat it up to a high temperature in air.
sohel2012 said:Hello everyone,
you same thing happened to me too, i used a becker for the container, carbon as electrodes, a 9 volt battery, and table salt. Then i saw the solution becoming yellow. Is it something with the salt? because i used table salt, which is iodised. the salt packing says 40 ppm of potassium iodide is mixed with the salt. can anyone shed some light on it? thanks.
mrjeffy321 said:Where did you get the carbon for the electrodes? I presume you scavenged it from somewhere, which could hint at what the contamination might be.
The yellowish color in a brine electrolysis solution is typically caused by the presence of impurities, such as iron or manganese, in the brine. These impurities can react with the electrolysis process and produce a yellow hue in the solution.
No, the yellowish color in a brine electrolysis solution is not harmful. It is simply an indication of impurities in the solution and does not affect the effectiveness of the electrolysis process.
Yes, the yellowish color can be removed from the brine electrolysis solution by using a filtration system. This will help to remove any impurities that are causing the discoloration. It is important to regularly clean and maintain the filtration system to ensure its effectiveness.
No, the yellowish color does not affect the production of chlorine in brine electrolysis. However, it is important to monitor and maintain the purity of the solution to ensure the efficiency of the electrolysis process.
The purity of the brine solution can be maintained by regularly testing and monitoring the levels of impurities in the solution. If necessary, a pre-treatment process can be used to remove any impurities before the solution is used for electrolysis. Additionally, proper maintenance and cleaning of the electrolysis equipment can also help to prevent discoloration in the solution.
