Lesson Plan: Removing Copper Stains from Masonry Mark as Favorite (9 Favorites)
In this lab, students investigate the use of milk of magnesia poultice to remove copper stains on masonry in copper architecture. They use chalk as the model for masonry, copper(II) chloride solution as a model for soluble copper and a freshly prepared slurry of copper phosphate as a model for a hard stain of copper on masonry. Through a series of investigations students have the opportunity to connect chemistry topics with real-world applications, such as environmental hazards, engineering practices of copper architecture, corrosion control, and structural protection.
