covering of another metal surface with another metal)‚ and the manufacturing of many kinds of chemicals such as chlorine‚ sodium chloride‚ and bleach. Also‚ electrolysis is used to extract reactive metals such as aluminium and the purification of copper. With these examples‚ we can say that electrolysis has many benefits‚ for example the manufacturing of bleach. Bleach can be used to clean household equipments‚ and to whiten/lighten or clean stains on white cloth. Other than that‚ there

Alps it was suggested that he was a Shepard or a hunter as he carried weapons with him * In samples taken of Otzi ’s hair‚ high levels of copper particles and arsenic were found. Scientists thought that he may have been involved in copper smelting possibly as part of his living. The copper axe that Otzi was found with was composed of 99.7 % pure copper. HOW DID OTZI DIE? When scientists were analysing new X-rays‚ they noticed a foreign item lodged in Otzi ’s left shoulder. Detailed investigations
