  1. Turn in your lab Agenda AQOD 8.3 Quiz Notes on Acids and Bases 9.1 Reading Guide HW: Finish Reading Guide How can you tell if a solution is unsaturated or saturated?

  2. ACIDS & BASES and the Ph scale

  3. Going To Extremes: Frozen Alive • http://vsx.onstreammedia.com/vsx/pbssaf/search/PBSPlayer?assetId=69032&ccstart=828002&pt=0&preview=undefined&entire=yes • Video

  4. Acids • -taste sour • are corrosive to metals • change blue litmus red • become less acidic when mixed with bases • -pH scale 1-6 • -have “H” as a common element

  5. Bases • feel slippery • have a bitter taste • change red litmus blue • become less basic when • mixed with acids • pH scale 8-14 • do not react w/metals

  6. The relationship between [H+] and pH is shown in the table below alongside some common examples of acids and bases in everyday life.

  7. An ACID produces hydrogen ions (H+) when dissolved in water. • A BASE produces hydroxide ions (OH-) when dissolved in water.

  8. ACIDSBASES

  9. The Ph scale • -Is used by scientists to determine how acidic or basic a solution is. • Ranges from 0-14 • Acid solutions have a Ph less than 7 • Base solutions have a Ph of greater than 7 • Neutral solutions have a Ph of 7 • Ph is measured by using indicators such as litmus paper or liquid indicators

  10. NEUTRALIZATION • When a base is used to make an acid • weaker, and vice versa. The neutralization reaction of an acidwith abasewill always produce water and a salt
