Belding Area Schools Standard Analysis Unit 2 Chemistry: Solutions STRAND: C STANDARD: See HSCE SUBJECT: Chem. B 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?
