Reactions and Neutralization in the Copper Cycle
A Cycle of Chemical Reactions of Copper PRE-LABORATORY ASSIGNMENT Finish the pre-laboratory assignments before the laboratory experiment. Read the manual of this experiment and complete the following questions. 1. a. Identify oxidation-reduction reactions in the copper cycle experiment. For each oxidation-reduction reaction, write half reactions to show what is oxidized and what is reduced. Identify acid-base reactions and precipitation reactions in the copper cycle experi- ment. Write equations for the corresponding reactions. b....

The first two pages are a background of the lab and there is a
page with the results. I would appreciate any help with this. If
needed I have the pre-lab questions as well. I added in the pre-lab
questions I will get them answered and updated again if that is
what is needed.
