Abstract

I was interested to learn how metals corrode under different conditions. By exposing certain metals to acids we know that they will corrode. In this experiment, we varied the temperature to learn how the corrosion rate changed. We found that as the temperature increased, the corrosion rate increased rapidly. We created three different conditions with three baths of ferric chloride and sodium chloride solutions at 61˚C, 32˚C and 20˚C. Aluminum strips were submerged in each solution for a period of 20 hours. We then measured the amount of corrosion from each aluminum strip from its base and then recorded the results. The strip submerged in the highest temperature solution was found to have the highest level of corrosion.
