Hi. I'm confused about how chlorine reacts with water. Yesterday I electrolised saltwater. There was some intense bubbling at 0V electrode. I guess that was hydrogen. However there was no bubbling at positive electrode. The water had been greenish at first but then some brown mud appeared. It's probably because I used iron electrodes or impurities because it was tap water with addition of salt. So did chlorine react with water immediately after it had been produced, hence no bubbling? How do they make chlorine via electrolysis if chlorine reacts with water?
