Presentation transcript:

 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

 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?

 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

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

 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)

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

 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

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

 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

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

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
