Verified step by step guidance1
Identify that the compound is a binary acid because it consists of hydrogen (H) and one other nonmetal element, iodine (I).
Recall that binary acids are named using the prefix 'hydro-', followed by the root of the nonmetal element's name, and ending with the suffix '-ic acid'.
Determine the root name of iodine, which is 'iod'.
Combine the prefix, root, and suffix to form the acid name: 'hydro' + 'iod' + 'ic acid'.
Conclude that the correct name for H I (aq) is 'hydroiodic acid'.
