Question

1. In step 1, of the cycle of copper reactions, explain how the color change of the solution confirms that the reaction is complete. 2. Knowing that you started with 0.5g of Cu, how does the mass of the recovered copper compare to the initial amount of Cu?( percent error) 3. Does the mass of recovered copper violate the law of Conservation of mass? Explain. 4. If you had a high percent error, what were some issues that may of lead to a high percent error? 5. How would you conduct the experiment differently, if you were to perform it a second time? 6. In step 5, zinc is added to the solution to replace the copper in solution. What could be another metal used in this step? Select a metal that would react with similar reaction time or faster. Explain.
