WebSulfuric acid is the strongest acid on our list with a pK a value of –10, so HSO 4- is the weakest conjugate base. You can see that hydroxide ion is a stronger base than ammonia … WebTherefore, hydroiodic acid is the strongest acid out of these four because hydroiodic acid has the lowest value for the pKa. If hydroiodic acid is our strongest acid, the conjugate base must be the most stable. So the conjugate base to hydroiodic acid would be the iodide anion, I minus. So here we have all of the different conjugate bases.
