A carbon steel plate is exposed to stagnant seawater containing dissolved oxygen and a corrosion rate of icorr = 6.0 x 10-5 A cm-² is measured. The molar mass of iron is M = 55.8 g mol-¹ and its density is p = 7.8 g cm-³. (a) What is the corrosion rate of the steel plate in mmpy? (b) A zinc plate is then electrically connected to the carbon steel plate and both are immersed in seawater. Which material will form the anode and which the cathode in the resulting galvanic couple? Justify your answer. (c) Write down the relevant anodic and cathodic reactions for (b). (d) Sketch the galvanic couple showing the anodic and cathodic reactions and the direction of the electron flow.
