Introduction

Specific Problem:

This experiment will attempt to determine weather aluminium will corrode at different rates if the temperature is varied.

Description of Experimental Strategy:

Using aluminium strips, I will place these strips in a solution of ferric chloride and sodium chloride (acids) for four days at temperatures of 70˚C, 35˚C and 20˚C. After the four day period the aluminium samples will be removed from the acid, rinsed and will be photographed and labelled. The amount of corrosion will be observed and recorded.

Statement of Purpose:

Corrosion of metals is important to understand because of the frequent use of metals in the construction of many items we use on a daily basis. For example automobiles, airplanes and hydro towers are good examples of the use of different metals which are exposed to varying temperatures and chemicals such as salts and acids. By understanding what chemicals and temperature range certain metals are exposed to then you can determine the rate of corrosion, the metal will under go. This will allow you to better select the right metal for the right job.
