Water properties

Water properties

  • Polarity
    water is a polar molecule with one oxygen atom negatively charged and two hydrogen atoms positively charged.
    water is a polar molecule with one oxygen atom negatively charged and two hydrogen atoms positively charged.
  • Universal solvent
    Water - due to its polarity and ability to dissolve other polar molecules
    Water - due to its polarity and ability to dissolve other polar molecules
  • Hydrogen bonds
    The weak intermolecular bonds that form between the hydrogen atom of one water molecule and the oxygen atom of another water molecule.

  • Solvent
    Does the dissolving

  • Solute
    Substance being dissolved

  • Solution
    Solvent +Solute=Solution
    Solvent +Solute=Solution
  • density
    the ratio of the mass of a substance to the volume of the substance (The density of water is 1.0 g/cm3)
    the ratio of the mass of a substance to the volume of the substance (The density of water is 1.0 g/cm3)
  • Polar Molecule
    a molecule in which one side of the molecule is slightly negative and the opposite side is slightly positive
    a molecule in which one side of the molecule is slightly negative and the opposite side is slightly positive
  • Buffer
    A solution that minimizes changes in pH when extraneous acids or bases are added to the solution. Proteins and Amino acids are intracellular fluid buffers. Carbonic acid/bicarbonate is an extracellular buffer. Hemoglobin / Oxyhemoglobin is an RBC buffer.
  • Cohesion
    Attraction between molecules of the same substance
  • Adhesion
    An attraction between molecules of different substances (water and another substance)
  • capillary action
    tendency of water to rise in a thin tube against the force of gravity, and due of the cohesion and adhesion forces of attraction.
  • Surface Tension
    An invisible film at the surface of water that allows objects to walk. This is caused by the cohesive forces.
  • high specific heat
    Water can absorb or release a tremendous amount of energy with little change in actual temperature. The ability of water to resist changes in temperature. 1 gram of water will need to absorb 4.18 Joules (amount of heat) in order to increase its temperature by 1 degree Celsius.

  • Acid
    any compound that forms hydrogen (H+) ions in solution
  • Base
    a compound that produces hydroxide ions (OH-) in solution
  • pH scale
    scale with values from 0 to 14, used to measure the concentration of H+ ions in a solution; a pH of 0 to 7 is acidic, a pH of 7 is neutral, and a pH of 7 to 14 is basic

  • Hydrophilic
    A substance that likes water. Having an affinity (love) for water; usually polar molecules.

  • Hydrophobic
    A substance that water hates water (it is repealed by water); usually non-polar molecules, like oil.
  • Homeostasis
    the process of maintaining the body chemical and thermal components in equilibrium. What hormone is responsible with maintaining the water homeostasis in human's body?
  • Liquid form of water
    water
  • Gas form of water
    water vapor or steam
  • Expansion upon freezing
    hydrogen bonds in ice are more "ordered and spaced out" making ice larger and LESS DENSE
