Acids Nomenclature Exercises


Ok, time to practice the Acids Nomenclature, this will help you through your school exams, and remember, anything can be achieved with a little practice.

Name these Acids with all 3 nomenclatures; remember to use the tricks we learned.

EXAMPLE

Name this Acid

HClO4

Remember how to make Acid formulas? Now we just need to go backwards to figure out which oxidation number the metal is using. Take the oxygen subscript, multiply it by 2 and subtract the Hydrogen subscript.
Proper way tod etermine the oxidation number of the No metal on the Acid


Now that we know which it is, let’s find the correct suffix to use. It has 4 oxidation numbers:

+1 ----> Hip-----ous
+3 ----> -ous
+5 ----> -ic
+7 ----> Per------ic

Traditional nomenclature has this writing structure:

[ELEMENT NAME][SUFFIX] Acid

So we just need to fill the name of the Non-metal and the suffix

PerChloric Acid


H2SO4

Sulfur has a valence of +6 on this Acid (4x2) – 2 = 6

Sulfuric Acid              <--- Traditional

HNO3

Nitrogen has a valence of +5.

Nitric Acid                 <--- Traditional

HClO

Chlorine has a valence of +1

Hypochlorous Acid                <--- Traditional

H2CO3

Carbon has a valence of +4

Carbonic Acid                                   <--- Traditional

HClO3

Chlorine has a valence of +5

Chloric Acid                                 <--- Traditional

I think you have an Error... on your last example.

HClO3

Here, Chlorine has a valence of +5, no?

Thus you would have Chloric Acid ?
