Chapter 13, Problem 13.44PAE
A magnesium bar with a mass of 6.0 kg is attached to a buried iron pipe to serve as a sacrificial anode. An average current of 0.020 A flows between the bar and the pipe. (a) What reaction takes place at the surface of the magnesium bar? (b) What reaction takes place at the surface of the iron pipe? (C) In which direction do electrons flow between the two surfaces? (d) How many years would it take for the entire magnesium bar to be consumed?
