Acids and Bases Notes for Chemistry 1 (TAMU CHEM120)
  • Acids and Bases Notes for Chemistry 1 (TAMU CHEM120)

  • Class notes • 7 pages • 2023
  • Notes taken on the topic of acids and bases as taught by Dr. Williamson in CHEM 120 at TAMU. These notes provide an all-around in-depth explanation of acids and bases. They begin with definitions of Lewis acids and bases as well as Bronsted-Lowry acids and bases. The rules for all these acids and bases are then described, showing the separation between strong and weak acids and bases. The rules across the periodic table are shown, describing the electronegative trend. The relation of these acids...

Buffer Notes for Chemistry 1 (TAMU CHEM120)
  • Buffer Notes for Chemistry 1 (TAMU CHEM120)

  • Class notes • 1 pages • 2023
  • Notes taken on the topic of buffers as taught by Dr. Williamson in CHEM 120 at TAMU. These notes show some examples of RICE tables used for buffers to calculate Ka, Kb, pH, and/or pOH. They then describe and show how to use the Henderson Hasselbalch Equation to calculate the pH or pOH of a buffer solution which is an imperative skill in chemistry. Finally, they describe how else these buffers are sued and other applications.

Electrochemistry Notes for Chemistry 1 (TAMU CHEM120)
  • Electrochemistry Notes for Chemistry 1 (TAMU CHEM120)

  • Class notes • 7 pages • 2023
  • Notes taken on the topic of Electrochemistry as taught by Dr. Williamson in CHEM 120 at TAMU. These Notes describe single displacement reactions and go well into depth on oxidation numbers and how to calculate them. It then furthers this idea by providing information on how to balance REDOX Equations stoichiometrically. The notes then move on to describing voltaic cells and the electrochemical cells and electrodes within. These cells are used to calculate cell potential using REDOX reaction rule...

Equilibrium Notes for Chemistry 1 (TAMU CHEM120)
  • Equilibrium Notes for Chemistry 1 (TAMU CHEM120)

  • Class notes • 3 pages • 2023
  • Notes taken on the topic of equilibrium as taught by Dr. Williamson in CHEM 120 at TAMU. These notes describe the equilibrium constant K and explores its magnitude, properties, variations, and formulas. It provides multiple equations such as gas laws and converting Kp to Kc. It then briefly shows how to use RICE tables and how Q (reaction quotient) relates to the K expression in a chemical reaction. Next, it explores this relationship again, but through Le Chatlier's Principle which describes th...
