How do you name #"HBr"# and #"HBrO"_3#?
1 Answer
A good way to figure this out is that "hydro" implies that the anion does not have an oxygen atom, and that you can analogize with the chlorine-based acids that you were probably given.
For example:
#"HCl"# : hydrochloric acid
#"HClO"# : hypochlorous acid
#"HClO"_2# : chlorous acid
#"HClO"_3# : chloric acid
#"HClO"_4# : perchloric acid
None of the acids above that contain oxoanions (such as
Furthermore, the halogens all form acids with similar names because they are all in the same group/family. So, they have analogous acid naming schemes:
#"HBr"# : hydrobromic acid
#"HCl"# : hydrochloric acid
#"HI"# : hydroiodic acid
From this, you should be able to figure out that you have:
#"HBr"# : hydrobromic acid
#"HBrO"_3# : bromic acid
