Unit 16

Cloud physical and chemical processes. From: Mölders and Kramm (2014)

Learning goal

After this unit students should be able to

  • Apply Henry’s law to determine dissolution of soluble trace gases
  • Determine ionization
  • Construct aqueous phase reaction chains and the temporal evolution of concentrations in droplets
  • Determine pH values
  • Analyze heterogeneous chemistry processes
  • Assess impacts of atmospheric trace gases on water of various systems

Being able to write gaseous-aqueous phase equilibrium, ionization, and aqueous phase reaction equations as well as dissolution rate, and ionization rate equations.

Students’ Tasks

  1. Prior to watching the video, review the section Raoult’s Law, and the sections on CCNs, diffusion, enthalpy and phase transitions as well as Dalton’s law as these concepts are fundamental for understanding of aqueous chemistry
  2. Watch this video on the material that will be discussed in class
    1. Read chapter 5.3 to (included) of Lectures in Meteorology
    2. Take notes and be able to present the material learned
    3. Create an equation and constant sheet with the equations and constants that you consider relevant for solving problems.
    4. Answer the questionnaire by 1500 AST the day before class.

    You can find the powerpoint presentation of this unit here.

    Worked problem (optional)

    This movie shows a worked problem how to determine changes between the gas phase and aqueous phase.

    Other resources

    This video explains the difference between S(IV) and S(VI).

    Class work

    In class, we will use the material learned to solve the problems given in this work sheet.
