2.  Acids are compounds that ALWAYS begin with Hydrogen (H + ) › With the exception of water (H 2 O)  Some acids have oxygen  Some acids DO NOT have oxygen Examples: H 2 SO 4 H 2 CO 3 HCl HNO 3 H 3 PO 4 H 3 NH 2 S HClO 3

3.  Binary › Acids that DO NOT contain oxygen Examples: H 2 SHClHCN  Oxyacids › Acids that have a polyatomic ion and DO contain oxygen Examples: H 2 SO 4 HClO 3 HNO 3  *The more oxygen’s present in the acid the stronger the acid  Which of the examples is the strongest? How do you know?

4.  Naming Acids WITHOUT oxygen: 1. Always use hydro- as a prefix 2. Name the element (or non oxygen containing polyatomic ion) 3. Change the ending to “ic” 4. Add acid for the second name HCl HydroChloric Acid

5. Binary Acid Compound: Name of the Acid HF HBr H2SH2S H3NH3N HCN

6.  Work the backwards 1. Determine the Anion 1. Imagine the “hydro” gone 2. Imagine the element’s (or polyatomic’s actual ending in place of the “-ic” 2. Put Hydrogen in front of the Anion 3. Drop and Swap the charges/numbers Hydrophosphic Acid H +1 P -3 H 3 P (H 3 P)

7. Acid NameHydrogen and its charge Anion and its charge Compound Hydroiodic AcidH +1 I -1 HI Hydrosulfic Acid (Hydrosulfuric Acid) H +1 Hydrofluoric AcidH +1 Hydrocyanic AcidH +1

8.  Acids WITH Oxygen 1. Determine what the polyatomic ion is 2. Change the ending › If it ends in –ate it becomes –ic  “I ate it and it was ic (icky)” › If it ends in –ite it becomes –ous  “It’s ite (aight) with ous (us)” 3. Add “Acid” as the second part of the name Examples: H 2 SO 4 – Sulfuric Acid H 2 SO 3 – Sulfurous Acid

9. CompoundWhat is the polyatomic What does the ending change to? Name of Acid H 2 CO 3 CarbonateicCarbonic Acid HNO 2 HClO 4 HC 2 H 2 O 2 H 3 PO 4 HBrO

10.  Working Oxyacids Backwards 1. Determine the polyatomic ion › Change –ic to –ate › Change –ous to –ite 2. Put a Hydrogen (H +1 ) in front of the anion 3. Drop and Swap the charges/numbers Phosphic Acid H +1 PO 4 -3 H 3 PO 4

11. Name of Acid: What does the ending change to? What is the polyatomic, its symbol and it’s charge? Compound: Nitric Acid-ate Nitrate/NO 3 -1 HNO 3 Chlorous Acid Carbonic Acid Hypobromous Acid

12. Name of AcidDoes it have a prefix? Does it have O 2 ? What is the ending? What is the element or polyatomic? Compound Hydrophophoric Acid YESNOicPhosphorous P -3 H3PH3P Nitric Acid Sulfurous Acid Hydroiodic Acid Carbonic Acid
