Weight loss approach was used to investigate the corrosion characteristics of
various metals found in varying concentrations of solutions containing acids. The
degree of these metals' corrosion in 1–5 M HCL solutions was investigated for 24
hours. The order of metal corrosion is zinc > galvanized iron > copper >, whereas the
order of aqueous media corrosion is HNO3
> H2SO4
> HCl. It has been observed that
increasing concentration increases the corrosion potential. Further investigation into the
dynamics of corrosion has demonstrated that the rate of reactivity in terms of metals
rises with increasing solution concentration when the half-life decreases.
