SEAWATER CHEMISTRY OUTLINE
IMPORTANCE / PERCENTAGES (Hydro Cycle)/ AVAILABILITY
UNIQUE PROPERTIES: See Table on Page 133
Only substance that occurs naturally in all 3 states within temp range at earth's surface.
Polar compound, hydrogen bonds
Ability to change its state (solid, liquid gas)
Dissolving ability (universal solvent)
Maximum Density is at 4 degrees Celsius, thermal expansion, lakes freeze from top down, not bottom up
Water is less dense in the solid state
Water has High Heat Capacity, changes temp slowly, latent heat of vaporization and fusion, moderates earth's climate, excellent coolant
High surface tension (droplets, bubbles)
Chapter 5: Unique properties of fresh water
Origin of Seawater???
Chapter 6: The six major constituents, trace elements
Salinity, normal, hypersaline, brackish
Changes in surface salinity
Sources of salts…….. Compare to river water
How salts removed?
The Principle of Constant Proportions
Conservative and Nonconservative Constituents
