The Solubility of KNO3 Vocabulary Solution A mixture where one substance is dissolved in another Solutesubstance being dissolved Solvent Substance doing the dissolving Solubility The given amount of solute that can be dissolved in a given amount of solvent at a given temperature. Saturated A solution that can hold no more solute Soluble A substance that will dissolve in water Insoluble A substance that will not dissolve in water Rate of Solution Increased by Stirring Increase surface area Heat Solubility Curves Drawn using regression line- average between points Used to gain information without going through experiment Can use to find various volumes of solvents and masses of solutes Key Points In the same volume of solvent the more solute you add the higher the temperature must be to dissolve all solute. The less solute you use in the same volume of solvent the cooler the temperature needs to be for the solute to dissolve The rate of solubility can be increased by: Increasing surface area (crushing) Stirring Heating solvent Inferences How might manufacturer use solubility to produce their products? How can using the incorrect amount of solute affect profits? If I have too much sugar in my tea, how can I get it to all dissolve without adding more water?
