Compare the pKa1 and pKa2 values you determined experimentally with the literature values of your text book (you will need to convert the text book Ka values to pKa’s). Calculate the percent differences between your experimentally determined values and the literature values (make sure you use the proper formula for calculating ""percent difference"").

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.
