● It decomposes at a high range of temperature and produces toxic fumes of hydrochloric acid (HCl) and disodium oxide (Na2O) while decomposing. ● It is known for being a good conductor of electricity in the aqueous state because of the free movement of the ions in the solution. ...
offers protection against acidic corrosion by retarding the corrosion process, if there is oxidative corrosion the presence of sulfides increases the likelihood of defects in the oxide lattice and thus destroys the protective nature of the natural (oxide) film, which leads to a corroded or pitted ...
