  1. Whats the 6 strong acid?
    • HCl, HBr, HI,
    • HNO3, H2SO4, HClO4
  2. Name all 6 acids
    • hydrochloric acid
    • hydrobromic acid
    • hydroiodic acid
    • nitric acid
    • sulfuric acid
    • perchloric acid
  3. hydroxides are considered...
    strong base.
  4. vapor pressure lowering
    if a liquid (substance 1) is added to another liquid (substance 2) to make a solution, then each liquid would have each its own vapor pressure (P1 and P2)
  5. increasing the temp. of the solvent does what to the solid?
    increases the solubility of dissolved solids
  6. increasing temp of solvent does what to gases?
    it decreases the soolubility of dissolved gases.
  7. increasing pressure of a gas above a soln does what to a gas?
    it increases the solubility of that gas.
  8. molarity =
    moles of solute/ volume of soln (mol/L) (M)
  9. molality =
    moles of solute/ kg of solvent - mol/kg (m)
  10. mole fraction =
    moles of component/ moles of total
  11. mass fraction =
    grams of component / grams of total
  12. weight % =
    grams of component / grams of total x100%


    mass fraction x100%
  13. Bronsted-Lowery acid.
    a substance that donates a proton
  14. Whats a proton donor?
    a Bronsted -Lowery acid
  15. examples of Bronsted-Lowery acid.
    HCl, H3O+
  16. Bronsted-Lowery base is...
    • a substance that accepts a proton
    • aka. proton acceptor
  17. example of Bronsted-Lowery acid.
    OH-, NH3
  18. strong acid is?
    • equation one direction
    • -donates 100%
  19. weak acid.
    • an acid that donates less than 100% of its protons to water
    • -equation is in equilibrium
  20. strong base is...
    • accepts 100% of pronts
    • -equation
