LOTS 10 Mr. P, Physical Science
Acid Have a pH lower than 7, turn blue litmus red, and chemical formula usually begins with “H”
Base Have a pH greater than 7, turn red litmus blue, and chemical formula usually ends in “OH”
Dilute To add more solvent to a solution in order to lower the overall concentration
Dissolve Physical change that describes a solute spreading out completely in a solvent to make a solution
Electrolyte Solute that, when dissolved, will conduct electricity
Heterogeneous Mixture Combination of at least 2 pure substances that do not mix
Homogeneous Mixture Combination of at least 2 pure substances that mix well and stay mixed
Immiscible Describes two substances that are not able to make a solution
Indicator Substance that changes colors based on pH
Insoluble Unable to dissolve
Miscible Describes two substances that are able to make a solution
Mixture Combination of 2 pure substances
Neutral Substances Have a pH of exactly 7, do not change litmus paper’s color, and are usually salts or pure water
Nonpolar molecule Substance that will not dissolve in water
pH Measure of the concentration of H+ in a solution
Polar molecule Substance that either IS water or will dissolve in water
Pure substance Either an element or a compound
Saturated Solution Homogeneous mixture where as much solute as can be dissolved has been added
Solubility Describes the grams of solute that will dissolve in 100 mL of water
Soluble Able to dissolve
Solute The substance in a homogeneous mixture that there is less of and spreads out in the other substance
Solution A homogeneous mixture
Solvent The substance in a homogeneous mixture that there is more of and allows solubility to happen
Supersaturated Solution A homogeneous mixture that is holding more solute than is normally soluble
Unsaturated Solution A homogeneous mixture that can hold more solute than it currently has
