Water Molecule Packet

Book Notes Review

Pgs. 54-57

slide2

Polar Molecule:

    • Molecule with a partial charge on opposite ends.
    • One end is slightly negative and the other end is slightly positive.
  • What makes a molecule polar?
    • Shared electrons are attracted more strongly to one atom than the other.
slide3

Solubility:

    • The ability of a polar molecule to attract opposite charges.
  • Give an example of something that can be dissolved by water:
    • Sugar or salt
  • Give an example of something that cannot be dissolved by water:
    • Oil, grease or wax
  • Hydrogen Bond:
    • The attraction between two polar molecules
slide4

Most unique properties of water result because:

      • Water molecules form hydrogen bonds with each other.
  • What causes Ice to float?
    • When water freezes into ice, empty spaces form between the water molecules making ice less dense than water.
  • Why does it take a long time for a large amount of water to change temperature?
    • Hydrogen bonds are constantly breaking and forming between water molecules causing water to absorb a lot of heat without changing temperature.
slide5

What is Cohesion?

    • The attraction between particles of the same substance. (water attracted to water)
  • What is adhesion?
    • The attraction between particles of different substances. (water attracted to a paper towel)
slide6

Solution:

    • A mixture in which ions or molecules of one or more substances are evenly distributed in another substance.
  • Water dissolves many ionic and polar substances but does not dissolve nonpolar substances.
  • Sometimes, water molecules break apart to form ions.
slide7

What acid does your stomach use to digest food?

    • HCl
  • What base is used to unclog drains?
    • NaOH
  • pH:
    • A measure of how acidic or basic a solution is.
  • Pure water has a pH of:
    • 7

Lemon: Acidic

Milk: Acidic/Neutral

Hand Soap: Basic

Vinegar: Acidic
