Vgtu Chemijos 7b laboratorinis Corrosion of metals (anglų kalba)
Chemijos laboratorinis darbas. Corrosion of metals. The aim and objectives Examine and test electrochemical corrosion mechanisms of metals in a variety of environments and write down the reactions for the corrosion of the anode and cathode, and their metal-ions. Theory. Chemicals. Equipment. Procedure. Corrosion of tin plated iron and zinc plated iron. Corrosion of iron nails in various solutions. Results. Conclusions During the laboratory work we have familiarized ourselves with the corrosion of tin plated iron and zinc plated iron and the Corrosion of iron nails in various solutions. We have determined that the PH of the solution determines where the corrosion occured and its intensity. During the corrosion of the tin-plated iron corrosion of iron occured,but in the case of zinc-plated iron the solution reacted with the zinc not the iron. Reference.
