dc.descriptionIn this paper, two simple ways of evaluating carbon steel sheet corrosion in a hydrochloric acid solution were presented as an experimental proposal for corrosion teaching. The first method is based on direct measurements of mass before and after corrosion tests. The second approach follows the principle of visual colorimetry by which soluble corrosion products are transformed into red complexes allowing monitoring of the products'concentration according to increases in solution color intensity. Both methods proved able to determine the corrosion rate.
