Naming Acids Warm Up: List a few acids that you are familiar with.
Hydrogen’s Role: • Acids are compounds that ALWAYS begin with Hydrogen (H+) • With the exception of water (H2O) • Some acids have oxygen • Some acids DO NOT have oxygen Examples: H2SO4 H2CO3HCl HNO3 H3PO4 H3N H2S HClO3
Two Different Types: • Binary • Acids that DO NOT contain oxygen Examples: H2S HCl HCN • Oxyacids • Acids that have a polyatomic ion and DO contain oxygen Examples: H2SO4 HClO3 HNO3 • *The more oxygen’s present in the acid the stronger the acid • Which of the examples is the strongest? How do you know?
Naming Binary Acids: • Naming Acids WITHOUT oxygen: • Always use hydro- as a prefix • Name the element (or non oxygen containing polyatomic ion) • Change the ending to “ic” • Add acid for the second name HCl HydroChloricAcid
Writing compounds from names: • Work the backwards • Determine the Anion • Imagine the “hydro” gone • Imagine the element’s (or polyatomic’s actual ending in place of the “-ic” • Put Hydrogen in front of the Anion • Drop and Swap the charges/numbers Hydrophosphic Acid H+1 P-3 H3P (H3P)
Naming Oxyacids: • Acids WITH Oxygen • Determine what the polyatomic ion is • Change the ending • If it ends in –ate it becomes –ic • “I ate it and it was ic (icky)” • If it ends in –iteit becomes –ous • “It’s ite (aight) with ous (us)” • Add “Acid” as the second part of the name Examples: H2SO4 – Sulfuric Acid H2SO3 – Sulfurous Acid
Writing Compounds from names: • Working Oxyacids Backwards • Determine the polyatomic ion • Change –ic to –ate • Change –ous to –ite • Put a Hydrogen (H+1) in front of the anion • Drop and Swap the charges/numbers Phosphic Acid H+1 PO4-3 H3PO4 H3PO4
