How do you make chlorine?
Theoretically, making chlorine is quite simple. All you need is water, salt, two conducting electrodes and electrons. That’s electricity, of course, and this electrochemical process is called electrolysis.
OK, in practice it is a bit more complicated and chlorine production plants are high-tech electrochemical facilities. They are built with state-of-the –art technology for maximum safety and environmental protection.
But basically, the process remains the same: you start with brine (a solution of salt in water) and you send an electric current through it. The products you will get are chlorine (gas), caustic soda and hydrogen - all basic but extremely useful chemicals that are used in hundreds of chemical and pharmaceutical processes.
