The Effects of Muriatic Acid & Copper | Career

Copper is often associated with noble metals for its resistance to non-oxidizing acids like muriatic (hydrochloric) acid. Copper is a not a noble metal per se like mercury, sliver, or gold, though it displays some of their properties in that copper will resist the degenerative reactions of muriatic acid in the absence of a catalyst. The catalyst in this case, is oxygen which bonds with copper
