Lesson 4: Properties of Solutions Containing Multiple Salts


In the first three lessons of this tutorial we examined the water content, phase state, and particle/vapour partitioning of single salt solutions, and mixtures containing both a salt and an acid. In the next three lessons we will study the behaviour of a two salt mixture. In this lesson we look at the water content at various relative humidities.


Before starting, ensure that this browser window occupies only the left half of your screen. You should leave enough space for another browser window where you can enter data into E-AIM and read the results. If your screen is too small for two windows, print out this tutorial and use this window to enter data and read E-AIM's results. In these lessons we assume that you will have two browser windows open.

Select this link to open a second browser window containing the data input page for "simple" calculations using Model III (http://www.aim.env.uea.ac.uk/aim/model3/model3a.php). Arrange the windows on your screen so that both are visible and the left window contains this text.

The Lesson

This consists of the two sets of calculations described in the links below, which should be done in the order listed.

   a.  Aqueous mixtures at fixed relative humidities
   b.  The Zdanovskii-Stokes-Robinson relationship


You have completed Lesson 4, and learned that:

Now proceed to Lesson 5, which examines how solids form in mixed aqueous aerosols.
