Nhi Vu General Chemistry- Agnes Rafoulko Conservation of Mass Introduction: This experiment will allow us to carry out various chemical reactions involving copper. Because no copper is added or removed during these processes, the entirety of the copper we began with should be recovered in the end due to the conservation of mass. Chemical Responsibility: The chemicals we are interacting with are toxic, corrosive and can cause severe skin burns and severe damage to the eyes. Thus it is necessary to wear glove and safety goggles. If we spill any of the chemicals on our skin, we must immediately flush the affected area with water for several minutes. Report Sheet: Materials : • Copper metal, nitric acid, sodium hydroxide, zinc Procedures : 1. Convert copper metal to copper nitrate by adding nitric acid to copper metal. 2. Convert copper nitrate to copper hydroxide by adding sodium hydroxide. 3.
