The Effects of Corrosion on Copper Piping

Overview

This experiment examined how well a homemade epoxy works compared to a store-bought epoxy in protecting copper rods from corrosion. The homemade epoxy was made using lightly burned MgO, Epsom salt, and tap water, and then applied to four copper rods. The other four rods were coated with store bought epoxy. All rods were submerged in 100 milliliters of tap water and monitored over time to see visible corrosion. The results showed that the store-bought epoxy did not provide the best results and corroded. The homemade epoxy did offer some protection but allowed more corrosion than the store bought product. This might be due to its weaker bonding strength and lower water resistance. The experiment suggests that homemade coatings can reduce corrosion to some extent. The store bought epoxy can help reduce corrosion as well to some extent.
