In the first part, samples of aluminum, copper and iron were immersed in concentrated sulfuric acid for ten minute intervals. After each ten minute interval, the weight of the samples were recorded. This process was done four times after which the corrosion rates were then found. Finally the corrosion rates versus the time were then plotted on a graph. In the second part of the experiment, a magnesium sample was connected to the apparatus and readings of the current were taken at regular intervals after which the graph of current versus time was plotted. Finally, the expected life of the magnesium anode was calculated for each reading. Part A (Corrosion)
