Transcribed Image Text:32 of 48
After learning about electrolytic cells, a student tries to copper-plate a metal spoon using a 1.00 M CuSO4
solution and 9V battery. However, instead of getting plated with copper, the spoon turns black and frothy white
bubbling covers its surface. Which explanation is most likely the case?
standard conditions were not maintained
the electrodes were connected in reverse
the salt bridge was left out
the voltage was too high
