Oxo-acids

Oxo-acids. Jason, Krystal, Pat, Jon. What is it?. Oxo-acid refers to any compound containing oxygen bound to hydrogen & at least one other element (non-metal). This combination forms; like the name says, an acid. **All acids are aqueous. Naming an acid. IMPORTANT!!!!

  1. Oxo-acids • Jason, Krystal, Pat, Jon

  2. What is it? • Oxo-acid refers to any compound containing oxygen bound to hydrogen & at least one other element (non-metal). This combination forms; like the name says, an acid. **All acids are aqueous

  3. Naming an acid • IMPORTANT!!!! • When naming your acid, follow these rules for changing the suffix of the polyatomic atom... • If it ends in:ITE your suffix becomes OUSATE your suffix becomes IC • Eg.Nitrate plus Hydrogen becomes Nitric AcidNitrite plus Hydrogen becomes Nitrous Acid

  4. Name➜Formula To go from the name to getting a formula:* Take acid name, and work back to the name of the polyatomic ion.*Take the formula for the polyatomic ion you found, with the charge, and add Hydrogen to form an acid.* “Cris-cross” the charges from the polyatomic ion and hydrogen. Remember ITE➜OUS ATE➜IC • Examples: • Nitric Acid➜Nitrate➜NO3-+H+➜HNO3(aq) • Sulfuric Acid➜Sulfate➜SO42-+H+➜H2SO4(aq) • Phosphorous Acid➜Phosphite➜PO33-+H+➜H3PO3(aq)

  5. Formula➜Name Remember ITE➜OUS ATE➜IC To go from a formula to getting a substance name:* Separate your formula into Hydrogen and one Polyatomic Ion, then “inverse criss-cross” to get the charges.* Take the name of your polyatomic ion, and change the suffix’s. Examples: HNO3(aq)➜H+ + NO3-(Nitrate)➜Nitrite=Nitrousacid H2SO4(aq)➜H+ + SO42-(Sulfate)➜Sulfate=Sulfuric acid H3PO4(aq)➜H+ + PO43-(Phosphate)➜Phosphate=Phosphoric acid.
