Prefix Hydro and Hypo
When exactly does the prefix hydro and hypo get added when naming compounds? I am a little confused after having reviewed my book.

A compound that starts with "hydro" is a binary acid (hydrochloric, hydroiodic, hydrosulphuric, hydrocyanic, etc) and does not contain oxygen. A
compound that starts with "hypo" is an oxyacid that has less oxygen than the standard model.
Chloric acid is HClO3, chlorous acid is HClO2, hypochlorous acid is HClO.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

More specifically, "hypo" is used in naming compounds with an oxyanion (AOx) where A is in its lowest oxidation state possible (>0)

Per*ic - a lot of oxygen
*ic - standard amount of oxygen
*ous - substandard amount of oxygen
hypo*ous - very low oxygen
hydro*ic - no oxygen
One exception: hydrogen peroxide is sometimes called hydroperoxic acid. It has oxygen. But this oxygen is the entire anion itself, it doesn't oxidize
some other element. Thus it is called the same as other single-element anion acids, "hydro".

This might be helpful as well, one of my previous explanations on this topic : http://www.sciencemadness.org/talk/viewthread.php?tid=25055&...
