  1. is the upper limit to the mass that can dissolve in a given volume of water
    solubility
  2. we can dissolve more solute
    unsaturated solution
  3. means  we have attained upper solubility limit
    saturated solution
  4. solubility is less than 1g/L. Amount that does dissolve is so small we do not notice
    insoluble
  5. solubility is generally at least 10 g/L
    soluble
  6. when you raise temperature of water, what will happen to solubility?
    increases
  7. does Gases dissolve better in cold water than in hot water
    yes
  8. what happen to solubility if you increase the pressure of the gas?
    solubility increases
  9. water- loving” § Participates in hydrogen bonds with water
    hydrophilic
  10. “water-fearing”  Cannot form hydrogen bonds and has little to no attraction to water
    hydrophobic
  11. Water-soluble vitamins
    vitamin C and B – can not be stored
  12. Fat-soluble vitamins
    A, D, E, K – can be stored
  13. is the amount of solute per the amount of solution
    concentration
  14. number of micrograms of solute in 1 mL of solution (µg/mL)
    parts per million
  15. number of nanograms of solute in 1 mL of solution (ng/mL)
    parts per billion
  16. is a measure of concentration.
    molarity
  17. is the process of adding water to reduce the solute concentration
    dilution
  18. is the amount of any ion that has the same total charge of 1 mol of hydrogen ions (H+). 
    equivalent
  19. is the tendency of particles to distribute evenly in a mixture
    diffusion
  20. are materials that allow only some particles to pass.
    semipermeable membrane
  21. is the net movement of water through a semipermeable membrane.
    osmosis
  22. is the relationship between the overall concentration of the solution and the normal solute of concentration in blood cells.
    tonicity
  23. is the movement of solute particles through a membrane
    dialysis
