One mL of an unknown solution is placed in a test tube and a few drops of NaOH are added and shaken well. 1 mL of aqueous NH3 is then added to the solution and shaken again. A deep blue solution is observed. What is the interpretation for this result? Select one: A. There is Iron(III) (Fe3+) present in the solution. B. There is Zinc (Zn2+) present in the solution. C. There is Copper(II) (Cu2+) present in the solution.
