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...
