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?
