Why rusting of iron is more in saline water than that of normal water ?

Posted byankushmasterPosted inchemistry

Rusting of iron is an electrochemical process , the presence of any ion facilitates the formation of rust. In saline water the presence of Na+ and Cl– ions increase the conductivity of the top layer of the iron , forming the Fe2+ ions . Thus the formation of Fe2O3 X H2O takes place quickly.
