Name: ___________________________ Due Date: ___________________________ Saturated and Unsaturated Solutions Saturated ● when no amount of stirring can make more solute dissolve Solution: in the solvent at the specific temperature Unsaturated ● when more of the solute could dissolve at the same Solution: temperature Solubility: ● the mass (amount) of a solute that can dissolve in a given amount of solute to form a saturated solution ● 35.7 g of salt will dissolve in 100 mL of ice water Solubility In Water Solute Temperature 0°C 20°C 50°C baking soda table salt sugar Supersaturated Solution: • a solution that contains more of the solute than would normally dissolve at a certain temperature • you can do this by preparing a saturated solution in a solvent at high temperature, then cooling it without stirring Adding a Seed Crystal to a Supersaturated Solution c) a) b) ________________ ________________ ______________________ ______________________ Pure Substances and Mixtures ____________________ ____________________ Page | 1 of 2 Name: ___________________________ Due Date: ___________________________ Analysis Questions 1.
