Question

naming binary acids
when naming acids, start by naming the anion. a monatomic anion, such as cl⁻, is simple named by replacing the ending of the element name with ide. for example, cl⁻ is named chloride and o²⁻ is named oxide.
once the anion is named, name the acid based on this anion. start by adding the prefix hydro, and then change the ide suffix to ic. for example, hcl would require the anion chloride to be changed to chloric. adding the prefix hydro creates hydrochloric acid.

naming oxoacids
oxoacids contain an oxygen atom in the anion. to name them, again, start with the name of the anion when naming acids. polyatomic anions are named according to the following rules:

• if an element can only form two oxyanions then the one with the least amount of oxygens is given the ending ite. the one containing the most oxygens is given the ending ate.
• elements that can form four polyatomic oxyanions use prefixes in addition to the ite and ate endings

Explanation:

Step1: Identify the anion

The anion in HI is $I^-$, which is named iodide.

Step2: Name the acid

Add the prefix "hydro -" and change the "ide" suffix of the anion to "ic". So the acid name is hydroiodic acid.

Answer:

hydroiodic acid
