Question

Given the following information about the activity series, select element(s)that could be used to protect the iron in a steel evaporative (swamp)cooler from corrosion. Cu < H₂ < Sn < Fe < Zn < Mg

Quizplus · Accepted Answer

This means that if they are placed in the same environment as iron, they will corrode instead of the iron. Therefore, using Zn or Mg sacrificial anodes is the best choice to protect the iron in a steel evaporative cooler from corrosion.
