  • Chemical Equilibrium and Solubility Equilibrium: Chapters 13 and 15

  • Acids and Bases: Chapter 14

  • Thermodynamics: Chapter 16

  • Electrochemistry: Chapter 17

Solutions

• Definition: A solution is a homogeneous mixture of two or more substances.

• Components:

  • Solvent: The component of the mixture in greater concentration.

  • Solute: The component present in a lower concentration.

• Example of Dissolution:
  $C<em>{12}H</em>{22}O<em>{11}(s) ightarrow C</em>{12}H<em>{22}O</em>{11}(aq)$

Types of Solutions

• Air:

  • Solute: O2(g)

  • Solvent: N2(g)

• Soft Drinks:

  • Solute: CO2(g)

  • Solvent: H2O(l)

• Hydrogen in Palladium:

  • Solute: H2(g)

  • Solvent: Pd(s)

• Rubbing Alcohol:

  • Solvent: H2O(l)

  • Solute: C3H8O(l) (2-propanol)

• Saltwater:

  • Solute: NaCl(s)

  • Solvent: H2O(l)

• Brass:

  • Solute: Zn(s)

  • Solvent: Cu(s)

Ionic Dissolution and Dissociation

• Example Reactions:

  • $ext{KMnO}<em>4(s) ightarrow K^+(aq) + ext{MnO}</em>4^{-}(aq)$

  • $ext{Na}<em>2 ext{SO}</em>4(s) <br>ightarrow 2 ext{Na}^+(aq) + ext{SO}_4^{2-}(aq)$

  • $(NH<em>4)</em>2CO<em>3(s) ightarrow 2 NH</em>4^+(aq) + CO_3^{2-}(aq)$

  • $$Al(NO3)3(s)
    ightarrow Al^{3+}(aq) + 3 NO_3^{-}(aq)

Thermodynamics of Dissolution

• Process Steps:

  1. Break solvent-solvent interactions (Endothermic process)

  2. Break solute-solute interactions (Endothermic process)

  3. Form solute-solvent interactions (Exothermic process)

• Discussion Points:

  • Identify Individual Intermolecular Forces (IMFs) being formed or broken when NaCl is dissolved in water.

Example of Cold Compress Activation

• Instructions for Use:

  1. Squeeze: Squeeze firmly until you hear a pop, causing the compress to cool.

  2. Shake: Mix the contents by holding each end and shaking.

  3. Apply: Apply promptly to the affected area.

• Caution: Single-use product, dispose after use. Store at room temperature. Do NOT freeze.

Homework Assignments

• Canvas Access: Review the entire syllabus

• Textbook Bookmarking: OpenStax Chemistry 2e

• Video Materials: Watch Week 1 videos and review key points from General Chemistry 1 as needed

• Worksheets: Practice and check work against answer keys on Canvas

• Calculator: Obtain a scientific calculator capable of scientific notation and logarithmic functions

• Recitation Overview: Familiarize with TA and review Molarity, mole calculations, and stoichiometry; recitation quiz #1 scheduled for the following week.
