Cu to Cu2+ Oxidation or Reduction
Cu 2 I - Cu I 2 Step 2. The first visible signs of oxidation occurred in about 2 min. Chapter 19 Electrochemistry Ppt Download An increase in oxidation state is oxidation eg Zn and a decrease in oxidation state is reduction eg CuII. . And identify what is being oxidized and what is being reduced. Which means Copper has lost 2 electrons. Cu Ag NO3- --- Ag Cu2 2NO3-Step 3.
