Naming Oxyacids
2

• 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.

• Examples

NO3- nitrate HNO3(aq) nitric acid
CO32- carbonate H2CO3(aq) carbonic acid
SO42- sulfate H2SO4(aq) sulfuric acid
PO43- phosphate H3PO4(aq) phosphoric acid
ClO3- chlorate HClO3(aq) chloric acid
C2H3O2- acetate HC2H3O2(aq) acetic acid
5

• Oxyacids form different acids by changing the
  number of oxygens

HClO4 perchloric acid one extra oxygen
HClO3 chloric acid normal formula
HClO2 chlorous acid one less oxygen
HClO hypochlorous acid two less oxygen

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.
