4. Word Wall Complete your Wordscramble and turn-in by Friday.

5. Acids and Bases

6. #66. Acids and Bases Foldable ACIDNEUTRALBASE

7. Acids and Bases Foldable Acids: Acids: Hydronium ion H + Tastes sour Changes Blue litmus to Red pH of 6.9 or lower Reacts with metals More H + → stronger acid

8. Acids Continued… H + + H 2 O = H 3 O + Examples: Orange Juice Lemon Juice Coffee Tea Soda Pop Vinegar pH: 0 - 6.9 Strong Weak

9. Neutral: Acid + Base = Neutral Substance Produces a salt and water H + + OH - = H2O Forms an ionic compound and water

10. Neutral Continued… H2OH2O Salt Examples: Sodium Chloride NaCl Magnesium Sulfate MgSO 4 Sodium Carbonate Na 2 CO 3 pH: 7 H2OH2O H + + OH -

11. Bases: Hydroxide ion OH - Tastes bitter Changes Red litmus to Blue pH of 7.1 or higher Feels slippery More OH - → stronger base

12. Bases Continued… OH - Examples: Window Cleaner Drain Cleaner Soap Toothpaste Mouthwash Cough Medicine pH: 7.1 - 14 Weak Strong

13. Exit Ticket Discuss with your group some properties of Acids? Bases?
