is it easy to distinguish between between the different oxidation states of copper? why?
-I answered yes because copper (I) is not as stable as copper (II), and there is a noticeable colour difference
You synthesized copper (I) chloride and copper (I) oxide. How do they differ from their copper (II) analogs? comment on the stability of these moist solids in air. If unstable, what is the likely product of decomposition?
-I'm not really sure where to go with this one, would it be something along the line of copper (II) is more stable than copper (I)?
calculate the percent recovery of copper from 10 mL of .10M of Cu(NO3)2? (how would you do this question?)
Percent recovery: Moles = Concentration * Volume .10 M * 10 mL = .10 M * .010 L = .001 mol Percent recovery = ((# of moles) * (molar mass of copper)) = .063546/.0191g =30 percent recovery
Is it necessary to synthesize the various copper compounds in order to recover copper metal?
I answered no, the metal can be extracted using less steps but the metal wont be as pure as it is using all the stpes
Also, how can you write word equations for reactions? For example, adding HCl to CuO.
