LARN 128 C32D4
Start the following in class:
1. When a solutes concentration is expressed in terms of molar concentration, the number of moles of solute in a given measured volume of liquid is directly proportional to the volume of the solution measured out. The required focus topic, J128, for today is
a. When the number of moles of solute in successive samples of the same solution are plotted against the increasing volumes of solution measured out, describe the shape of the graphed relationship. Give an example to clarify what you are saying and explain how your example demonstrates the concept being considered.
b. When the number of moles of solute in successive samples of the same solution are plotted against the increasing volumes of solution measured out,what does the value of the slope of the plotted line correspond to? Give an example to clarify what you are saying and explain how your example demonstrates the concept being considered.
2.a. Use the PQ5R or SQ5R method...
LARN 127 C32D3
Start the following in class:
1.a. The required focus question, J127A, for today is
Some procedures affect the rate at which a given amount of solute will dissolve in a given amount of solvent and some procedures can affect the maximum amount of solute that can dissolve in a given amount of solvent at a given temperature (i.e. can affect the solubility of the solute in that solvent at that temperature).
a. Describe the typical effects on the rate at which a solute dissolves, if any, of
stirring or agitation of the solute and solvent mixture,
increasing the temperature of the solute and solvent mixture,
decreasing solute particle size before mixing it with the solvent, and
increasing the partial pressure of a gaseous solute on the rate of dissolution of the solute.
b. Describe the typical effects on the maximum amount of solute that can dissolve in a given amount of solvent, if any, of
stirring or agitation...
