Chemical process using electric current commonly called as electrochemical, but for general people this name may don’t familiar. Named by Electrochemical because on the process involved the chemicals and electrical, so the whole process called as electrochemical. Electrochemical is not just happened in plant or industry or laboratory, this process also always happened in nature. This process can go and trigger by any different voltage surround the chemicals substance. The different voltage on the environment of certain substance can Electrochemical Cell cause the reaction happened. For example the process of corrode, because of any voltage different make iron that stick to copper can be corroded faster than other metal that don’t stacked to copper metal. This condition used to happen on Air Conditioner tubing. Other metal in AC corroded faster than other iron on other product. Now this condition have been avoided by replace the metal with plastic material. On the process of e...
