3.22.10 - Guide to Naming and Writing Formulas for Chemical Compounds

Given: H3P Name: hydrophosphoric acid


 * Since this formula starts with hydrogen, I know that it will be an acid. Phosphorous ends with -ide, so that makes hydro- end with the suffix -ic. I did this by using the first rule to naming acids.



Given: carbonic acid Formula: H2CO3


 * To find the formula for carbonic acid, I used rule 3 for naming acids. Since the hydrogen is bonded to carbonate, the -ate ending changes to -ic. The charge on carbonate is (2-). This means that hydrogen will have a (2+) charge in order to balance out.



Given: cobalt (III) sulfate Formula: Co2(SO4)3


 * The formula for cobalt (III) sulfate is Co2(SO4)3. Since sulfate has a (2-) and cobalt has a (3+), you cross the 2 over to cobalt, and the 3 to sulfate.
