17 flashcards · Physics · by Samvid Konchada

  1. A substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions. i.e. sulfuric acid

    acid

  2. a substance that in water solution is slippery to the touch, tastes bitter, changes the color of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions. i.e. soap

    base

  3. High amount of solute in solvent i.e. dead sea

    concentrated

  4. Low amount of solute in solvent i.e. tap water (small quantities of dissolved minerals)

    dilute

  5. a quantitative measure of the acidity or basicity of aqueous or other liquid solutions. i.e. pH level of 7

    pH

  6. degree to which a substance dissolves in a solvent to make a solution i.e. amount of salt that can dissolve in boiling water

    solubility

  7. a homogenous mixture of two or more substances i.e. apple juice

    solution

  8. when a solvent has less solute dissolved in it than total possible i.e. saltwater that can still have more salt dissolved in it

    unsaturated

  9. Having a pH greater than 7 i.e. bleach

    alkaline

  10. the measure of the ease at which an electric charge or heat can pass through a material i.e. wire that conducts electricity

    conductivity

  11. minerals in your blood and other body fluids that carry an electric charge i.e. sodium

    electrolytes

  12. when a solvent has the maximum amount of solute dissolved in it that is possible i.e. water that no more salt can be dissolved in

    saturated

  13. substance, ordinarily a liquid, in which other materials dissolve to form a solution i.e. water in saltwater

    solvent

  14. A line on a phase diagram that gives the limits of solute addition i.e. the solubility curve of water

    solubility curve

  15. a compound found in bases i.e. OH- in soap

    OH-

  16. a scale used to measure acidity and basicity i.e. water has is 7 on the pH scale

    pH scale

  17. When concentration of a solute exceeds the value for saturation i.e. when more salt is dissolved in water than normally possible

    supersaturated
