Unformatted text preview: Name: ___________________________________ CH101 Solutions and Solubility – Study Guide sections 12.2 and 12.4 in the textbook Solubility (section 12.2) Solubility for solids and liquids generally _____________________ (increases, decreases) with increasing temperature. Solubility of gases generally ________________________ (increases, decreases) with increasing temperature. Saturated and Unsaturated Solutions (section 12.2) A solution containing more than the maximum amount of solute at a given temperature is called _________________ (saturated, supersaturated, unsaturated). example: The solubility of sodium acetate is 46.4 g/100 mL water at 20oC. Describe each of the following solutions as unsaturated, saturated or supersaturated. 49.3 g/100 mL __________________________________ 21.6 g/100 mL __________________________________ 46.4 g/100 mL __________________________________ Factors Affecting Solubility (section 12.4) The primary rule of solubility is “Like dissolves like,” which originates from the idea that a polar solute is more likely to dissolve in a _______________ (polar, nonpolar) solvent.
