Oxyacids are acids made up of hydrogen, oxygen and one other element and produce H+ ions when dissolved in water. • Many of the common polyatomic ions become oxyacids by adding hydrogen. • The suffix “-ate” becomes “-ic” and the word acid is added to the end.

Oxyacids – form different acids by changing the number of oxygens
Examples • What is HNO3? • nitric acid • What is HNO2? • nitrous acid • What is HNO4? • pernitric acid • What is HNO? • hyponitrous acid
Extra • Recall that “-ate” ions become “-ic” acids. • Likewise, “-ous” acids become “-ite” ions • HClO2 is chlorous acid; ClO2- is the chlorite ion. • HClO is hypochlorous acid; ClO- is hypochlorite ion.
Examples • What is HNO3? • nitric acid • What is NaNO3? • sodium nitrate • What is HNO2? • nitrous acid • What is NaNO2? • sodium nitrite
