    Heated
    Agitated
    Stirred
    Cooled
  • Part 9: Which is NOT one of the 3 factors that increase the solubility of a SOLID solute in liquid solvent:
    increase pressure
    incease surface area (i.e. crushing)
    increase agitation (stirring, shaking, mixing, etc)
    increase temperature
  • Part 9: 15 g of sugar cubes are dissolved in 120g of water at 20 C. What could be done to increase the rate of dissolution?
    Use larger sugar cubes
    Add an electrolyte to the water
    Stir the mixture
    Cool down the water
  • Part 8: Match the right description to the picture
    weak electrolyte
    Fully dissociated

    glycerol, C3H5(OH)3
    ethyl alcohol, C2H2OH
    potassium iodide, KI
    sucrose, C12H22O11
  • Part 8: In order for a substance to conduct electricity... (which is not true?)
    It will have to be in solid form
    it will have to be dissolved in water
    it will have to be an ionic substance
  • Part 9: 110 g of Pb(NO3)2 dissolved in 100g of water at 60 C would be considered____________
    an unsaturated solution (U)

    a saturated solution (S)
  • Part 8: Match the right description to the picture
    HCl
