  1. LOTS 10 Mr. P, Physical Science

  2. Acid Have a pH lower than 7, turn blue litmus red, and chemical formula usually begins with “H”

  3. Base Have a pH greater than 7, turn red litmus blue, and chemical formula usually ends in “OH”

  4. Dilute To add more solvent to a solution in order to lower the overall concentration

  5. Dissolve Physical change that describes a solute spreading out completely in a solvent to make a solution

  6. Electrolyte Solute that, when dissolved, will conduct electricity

  7. Heterogeneous Mixture Combination of at least 2 pure substances that do not mix

  8. Homogeneous Mixture Combination of at least 2 pure substances that mix well and stay mixed

  9. Immiscible Describes two substances that are not able to make a solution

  10. Indicator Substance that changes colors based on pH

  11. Insoluble Unable to dissolve

  12. Miscible Describes two substances that are able to make a solution

  13. Mixture Combination of 2 pure substances

  14. Neutral Substances Have a pH of exactly 7, do not change litmus paper’s color, and are usually salts or pure water

  15. Nonpolar molecule Substance that will not dissolve in water

  16. pH Measure of the concentration of H+ in a solution

  17. Polar molecule Substance that either IS water or will dissolve in water

  18. Pure substance Either an element or a compound

  19. Saturated Solution Homogeneous mixture where as much solute as can be dissolved has been added

  20. Solubility Describes the grams of solute that will dissolve in 100 mL of water

  21. Soluble Able to dissolve

  22. Solute The substance in a homogeneous mixture that there is less of and spreads out in the other substance

  23. Solution A homogeneous mixture

  24. Solvent The substance in a homogeneous mixture that there is more of and allows solubility to happen

  25. Supersaturated Solution A homogeneous mixture that is holding more solute than is normally soluble

  26. Unsaturated Solution A homogeneous mixture that can hold more solute than it currently has
