Electrolysis

In 1800 electric battery found by Volta, so after that time the people did the experiments to flow electric charge with others material, for example copper or other liquid material likes water or brine.

clorin electrolysis

When electric current flow through the brine, electrolysis reaction can decomposes the brine so created chlorine gas at anode plate and Sodium metal at cathode but it more easy to understand about electrolysis reaction if we look at electrolysis on the water.



If the water on glass dipped by two metal, one metal connected to positive side of battery and another metal connected to negative side.

The water can decomposes created bubbles of hydrogen gas on negative plate and oxygen gas on positive plate.

Negative plate next we call cathode and the hydrogen gas lay on cathode which has positive ion call anion. In another plate which positive plate we call anode and oxygen gas which has negative ion call cation.

h2 plant

In the power station, hydrogen gas is using for generator cooler and chlorine gas is using for poison for biota and microbiological content on sea water which flow as condenser cooler, The chlorine gas is not for kill the biota and microbiological but for avoid to growth inside condenser.
