The conjugate acid of ClO4- is HCIO4. B. HCL HCIO2 CIO3-2 HCIO3
The Correct Answer and Explanation is:
The correct answer is HCIO4.
Here’s why:
When you look at the conjugate acids of a given base, the acid is formed by adding a proton (H+) to the base. In this case, ClO4- is the base, and its conjugate acid is formed by adding a proton to it.
- ClO4- is the perchlorate ion, and when it accepts a proton, it becomes HCIO4, which is perchloric acid.
- The other species listed are not conjugate acids of ClO4-:
- HCl is hydrochloric acid, which is unrelated to ClO4-.
- HCIO2 is chlorous acid, which is the conjugate acid of ClO2-, not ClO4-.
- CIO3- is the chlorate ion, and HCIO3 is chloric acid, which is the conjugate acid of CIO3-, not ClO4-.
In summary, when ClO4- (perchlorate ion) gains a proton, it becomes HCIO4 (perchloric acid). This makes HCIO4 the conjugate acid of ClO4-.
