Today's worldwide installed capacity of 76.8 million tons of chlorine is produced through the electrolysis of concentrated solutions of sodium chloride, (brine), with three different technologies that have developed in time: mercury, diaphragm, and ion exchange membrane. For the last 20 years, ...

What happens during the electrolysis of sodium chloride? When an electric current is passed through concentrated sodium chloride solution,hydrogen gas forms at the negative electrode, chlorine gas forms at the positive electrode, and a solution of sodium hydroxide also forms. ...

Thus basically, an electrolysis cell is a galvanic (electrochemical) chain obtained (in the simplest and most common case) by the series connection of three different phases, one electronic conductor, one ionic conductor and a second electron conductor. From: Advanced Membrane Science and Technology...
The H2O2 in turn is capable of oxidizing the resulting copper (I) chloro-complex. Just another demo of the reactiveness of the copper-chloro complex.Take some household aluminium-foil and put this in a concentrated solution of sodium chloride (table salt). You'll see no reaction.Put some ...
The membrane is made from water-permeable polytetrafluoroethylene and is immersed in concentrated potassium hydroxide, which acts as a “self-dampening” electrolyte (SDE). This construction facilitates the spontaneous and continuous diffusion of pure water vapour from the less salty seawater through the...
we review recent advances in the rational design of chlorine-suppressive catalysts and integrated electrolysis systems architectures for chloride-induced corrosion, with simultaneous enhancement of Faradaic efficiency and reduction of electrolysis’s cost. Furthermore, promising directions are proposed for durab...
