Q1. Copper rivets were put into the hull of an iron ship
because copper was unreactive. Explain why this was not a good idea.
Cu2+(aq) + 2e- = Cu Eo =
+ 0.33V
Fe2+(aq) + 2e- = Fe Eo
= - 0.44V
Q2. Magnesium is used in distress flares. Explain if it
more likely or less likely that the distress flares will be needed on a steel
ship if more magnesium is attached to the hull of the ship?
Mg2+(aq) + 2e- = Mg Eo =
-2.38V
