Whats the name for HI(aq)?
I thought it was Hydrogen Iodide, but that's incorrect, does the aq change the name?
HCl(aq) is hydrochloric acid. The gas is hydrogen chloride.
HI(aq) is hydroiodic acid. The gas is hydrogen iodide.
Yes, the "(aq)" indicates that the compound is in aqueous solution, meaning it is dissolved in water. In this case, "HI(aq)" stands for Hydroiodic Acid.
To determine the name of a compound, you can break it down into its constituent ions or elements. In this case, "HI" refers to Hydrogen (H) and Iodine (I). When dissolved in water, hydrogen iodide forms hydronium ions (H3O+) and iodide ions (I-). Since the compound is an acid, it is typically referred to as Hydroiodic Acid when in aqueous solution.
So to recap, the name of the compound HI(aq) is Hydroiodic Acid, with the "(aq)" indicating it is dissolved in water.
