Four species are listed below: (`i`) `HCO_(3)^(-)` (`ii`) `H_(3)O^(+)` (`iii`) `HSO_(4)^(-)` (`iv`) `HSO_(3)F` Which one of the following is the correct sequence of their acid strength?A. `ivltiiltiiilti`B. `iiltiiiltiltiv`C. `iltiiiltiiltiv`D. `iiiltiltivltii`

Answer» Correct Answer - C
The `pK_(a)` values of `HCO_(3)^(-), H_(3)O^(+)` and `HSO_(4)^(-)` are `10.25, -1.74` and `1.92` respectively and `HSO_(3)F` is super acid.
