The conjugate acid of #I^-# is #HI#, hydroiodic acid.

Explanation:

Note that when you speak of conjugate acids/bases etc. you must be mindful of charge as well as mass. If we remove a (formally) proton from #HI# we remove #H^+# we remove charge as well as mass, hence the species left behind is #I^-#.

What are the conjugate acids of #F^-#, #SO_4^(2-)#, and #NO_3^-#. Which is the strongest conjugate acid?
