Account for the acidic nature of HCIO_4. In terms of Bronsted - Lowry theory, identify its conjugate base. |
|
Answer» Solution :(i) The acidic character of oxy of chlorine increases with increase in oxidation number of HALOGEN ATOM. The oxidation number of chlorine in `HCIO_4` (per chloric acid) is 7. Increase in oxidation number weakness the `O-H` bond strength and increases the acidity. Therefore `HCIO_4` is a strong acid. (ii) According to Bronsted - Lowry theory. removal of HYDROGEN ion or a proton froman acid is its conjugate BASE. (iii) So the conjugate base of `HCIO_4` is `CIO_4^(-1)` |
