Formulas for Oxyacids:
Write the formulas that correspond to the names nitric acid and
We recognize these as names of oxyacids,
because they have the forms (root)ic acid and root(ous) acid.
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.
