Which transformation could take place at the anode of an electrochemical cell? which transformation could take place at the anode of an electrochemical cell? o2 to h2o cr2o72- → cr2+ f2 tof− haso2 to as none of the above could take place at the anode.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
