Step 1:I'll solve this step-by-step using the guidelines you specified:
Step 2:: Understand the Definition of Conjugate Acid
- A conjugate acid is formed when a base accepts a proton ($$\mathrm{H}^{+}$$)
- We need to determine which species is formed by adding a proton to \mathrm{HSO}_{4}^{-}
Step 3:: Analyze the Possible Structures
- $$\mathrm{HSO}_{4}^{-}$$ is a hydrogen sulfate ion
- Adding a proton means increasing the number of hydrogen atoms by 1
Step 4:: Identify the Correct Conjugate Acid
- When $$\mathrm{HSO}_{4}^{-}$$ accepts a proton, it becomes $$\mathrm{H}_{2}\mathrm{SO}_{4}
- This matches the second option in the table
Step 5:: Verify the Chemical Logic
- $$\mathrm{HSO}_{4}^{-} + \mathrm{H}^{+} \rightarrow \mathrm{H}_{2}\mathrm{SO}_{4}
- The proton addition increases the hydrogen count from 1 to 2
Final Answer
\mathrm{H}_{2}\mathrm{SO}_{4} is the conjugate acid of \mathrm{HSO}_{4}^{-}.
