EXAMPLE- Formulas for Oxyacids:  

Write the formulas that correspond to the names nitric acid and nitrous acid.


We recognize these as names of oxyacids, because they have the forms (root)ic acid and root(ous) acid.

HNO3. Nitric acid is a very common acid, one whose formula, HNO3, you ought to memorize. You can also figure it out from the formula for nitrate, NO3-, by adding enough H+ ions to neutralize the charge. HNO3 is used to manufacture fertilizers and explosives and in the reprocessing of spent nuclear fuel.

You may not remember the formula of nitrous acid, but you can determine it from the formula for nitric acid, HNO3. The oxyacid with the name (root)ous acid has one less oxygen atom and the same number of hydrogen atoms as the (root)ic acid. Nitrous acid is HNO2.
