How do we use chlorine, hydrogen and sodium hydroxide in industry???
I’m sure other Yahoo answerers can let you know of other uses but here is one use for each of the above: Chlorine is one of the most highly reactive elements and will combine with many other elements and compounds. It used to be used in tiny amounts as an additive to control the growth of shellfish in sea water which is used to cool machines in industry but chlorine (a lethal gas used in war), is too poisonous to be stored safely as a liquid. Instead a chlorine compound like sodium hypochlorate can be added in small amounts to make it difficult for shellfish to multiply inside the pipes of these cooling systems. Hydrogen is the tiniest of all the atoms and is so fast and mobile that it is used, at a pressure of two or three atmospheres, as a cooling gas for the moving parts in large electrical machines like power station alternators. There the huge spinning rotor loses its heat to the hydrogen and less than a thousandth of a second later those hot hydrogen atoms have travelled to a wat
