Unit 2
I can investigate the difference in the boiling point or freezing point of pure water and a salt solution. (C4.7a)
I can determine how different physical factors (heating, stirring, crushing) will affect the rate of dissolving a solid.
I can determine how different factors (nature of the solute and solvent, temperature, pressure) affect solubility.
I can determine the concentration of a solution using molarity, molality, and percent.
I can determine how much of an original solution will be needed to make a new solution that is diluted to a
different molarity.
Enduring Understanding(s):




Different physical factors (heating, stirring, and crushing) affect the rate at which a solute dissolves in an
aqueous solution.
Different factors affect the solubility of a solute in a solvent.
Concentration can be expressed as molarity, molality, or percent.
Solutions can be diluted to new concentrations.
Essential Questions(s):




How does heating, stirring and crushing affect the rate that a solute dissolves in a solution?
How does the nature of the solute/solvent, temperature and pressure affect solubility?
How can the concentration of a solution be expressed?
How are solutions diluted to new molarities?
