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.

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
