  1. 1. Nomenclature PO 4 3- phosphate ion C 2 H 3 O 2 - acetate ion HC 2 H 3 O 2 Acetic Acid Chemistry 1: Chapter 9 Chemistry 1 Honors: Chapter 4 ICP: Chapter 20 SAVE PAPER AND INK!!! When you print out the notes on PowerPoint, print &quot;Handouts&quot; instead of &quot;Slides&quot; in the print setup. Also, turn off the backgrounds (Tools>Options>Print>UNcheck &quot;Background Printing&quot;)!
  2. 2. Common Names <ul><li>A lot of chemicals have common names as well as the proper IUPAC name. </li></ul><ul><li>Chemicals that should always be named by common name and never named by the IUPAC method are: </li></ul><ul><ul><li>H 2 O water, not dihydrogen monoxide </li></ul></ul><ul><ul><li>NH 3 ammonia, not nitrogen trihydride </li></ul></ul>
