Question 1 This question carries 20% of the marks for this assignment. In total, your answer should be no more than about 500 words long. a.Table 1.4 from Block 5, Part 1 (p. 34) – reproduced below – shows the measured potentials, relative to mild steel, for metals in brine and in beer. For the following combinations of metals, determine the cell potential and hence indicate which metal will corrode: i.a porthole made from brass set into a mild steel housing on an ocean-going ship ii.a stainless steel pipe that carries beer and is connected to a copper tank iii.a titanium bolt holding a flange made from aluminium, located in a brewery.
