When examining the titrations of hydrochloric acid and acetic acid with naoh, we notice that the equivalence point of the hcl solution occurs at a ph of 7.00, while the hch3cooh solution has an equivalence point around ph 8.72. suppose that the hydrochloric acid solution initially contained 10 mol of hcl, while in the acetic acid solution, 10 mol of hch3cooh were present initially. at the equivalence point, which solution contains more naoh?

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.
