Corrosion to Corals
Students will be able to describe galvanic exchange and explain how this process produces electric currents. Given two dissimilar metals and information on their position in an Electromotive Series, students will be able to predict which of the metals will deteriorate if they are placed in a salt solution. Students will also be able to describe the effect of electric currents on the availability of metal ions, and how this might contribute to the growth of corals on shipwrecks.
