L3 - WATER
STRANGE PROPERTIES
High Heat capacity
High surface tension
High density
Freezes from the top to bottom
floats
max at 4 degrees C
Highest conc. of 55.5 mol L^-1 at 25 Degrees
INDUCES DD IN NON-POLAR
Become Slightly charged Molecules
Even if molecules like O2 or N2 aren't very soluble
14 forms of ice
Electrolytes
Dissolves well
ions formed in the water
WEAK
Not fully
dissociated ions
STRONG
Fully
dissociated ions
POLAR
Dissolves
Polar
&
ionic
molec.
O>H electronegativity
O=more negative
H=More Positive
Electron pairs equally shared
Depends on e- Number & GAS molec.
SOLVATION
Stabilizes ions
Charged ions surround H2O
Non-Electrolytes
No ions
DISSOLVE
