Inorganic Reactions: Oxides Exercises

As we saw in my last post, oxides are very easy to name, I need to remark that these aren’t the only compounds where oxygen is, SIMILAR to oxides there are the Anhydride Compounds and they follow the SAME RULES as oxides but are made with NON-METALS.

Coming back to the exercises:

Name these oxides with all 3 nomenclatures:

K2O

Potassium has a valence of +1

Potassium Oxide                    <--- Traditional
DiPotassium Monoxide         <--- IUPAC
Potassium(I) Oxide                <--- Stock

Fe2O3

Iron has a valence of +3 in this oxide

Ferric Oxide                           <--- Traditional
diIron trioxide                                    <--- IUPAC
Iron(III) Oxide                       <--- Stock

Na2O

Sodium has a valence of +1

Sodium Oxide                                    <--- Traditional
Disodium Monoxide              <--- IUPAC
Sodium(I) Oxide                    <--- Stock

CaO

Calcium has a valence of +2

Calcium Oxide                       <--- Traditional
Calcium Monoxide                <--- IUPAC
Calcium(II) Oxide                 <--- Stock

Cr2O3

Chromium has a valence of +3

Chromic Oxide <--- Traditional
DiChromium Trioxide<--- IUPAC
Chromium(III) Oxide<--- Stock

Why did you write potassium has a valence of +1 with the Na, Ca and Cr?
