Title: Overview of Acids and Bases
Description: Chemistry
April 15, 2020

One unit of study done. I heard some positive comments and a few suggestions on how to improve things.
     Homework will continue to be assigned and not collected unless we return to school. I doubt very much we will return to school.
     The only points for the unit will be the test. The first test was only 20 points. If the score lowered your grade it was entered as a no count - otherwise the test score will count.
     It will take maturity on your part to practice the skills and keep up with the course.
     You can pause the videos at any time and go back later if they are too long for one sitting.
    
Feel free to work ahead on the calendar. Everything is set and all videos are loaded for the remainder of the year.

         If you have specific questions - please ask.



LEARNING OBJECTIVES:
     1) Define acids and bases (both Arrhenius and Bronsted-Lowry).
     2) List properties of acids and bases.
     3) Have a basic understanding of the magnitude of numbers on the pH scale.
     4) Identify a substance as an acid or base using pH values.

  OPTIONAL video(s) from Annenburg Learner:    Acids and Bases: The Voyage of the Proton
        "Acids and bases are important to many chemical processes: maintaining a stable internal environment in the human body, baking a delicious cake, or determining whether a lake can support aquatic life. Reactions involving acids and bases can be described through the transfer of protons – single H+ ions. For chemists, the number of those acidic hydrogen ions can be quantified by using the pH scale. The reactions of acids and bases, which can be monitored with indicators, can range from corrosive behavior to neutralizations that leave no acids or bases behind. To understand the controlling of pH of solutions, buffers are discussed in the laboratory and in the chemistry of the bloodstream."
