1. Explain/Discuss what a colligative property is. Provide at
least 2 examples of colligative properties.
2. Provide at least one real-life application of freezing point
depression.
3. Define the concentration term molality (m). Under what
conditions are Molarity and molality approximately the same?
4. Discuss/Explain why the temperature of a substance remains
relatively constant during the freezing of liquid to solid.
experiment: colligative properties
Water cannot be used as the solvent for this experiment. For
what types of molecular substances - give specific examples - could
water be used as a suitable solvent to determine a molecular
weight?
Can water be used to determine the formula weights of all ionic
compounds? What are the limitations, if any?
Why does the slope of the mixed solution continue to decrease
rather than reaching a plateau like that observed for the pure
liquid? Hint:...
1.Briefly explain four colligative properties. Your explanation
should contain the following:
a)definition of property
b)does it increase or decrease with concentration
c)what mathematical equation links the property to
concentration
d)At least one example of natural applications of the
property
For this activity, you will select one of the four module
objectives from the Module 8 Overview and Objectives page
1. Analyze International Trade Theory.
2. Examine trade restrictions and their effectiveness.
3. Discuss the foreign exchange market.
4. Distinguish between fixed and flexible exchange rate
systems.
