POLAR VS. NONPOLAR SUBSTANCES
Density Column:
ethanol
oil
After
water
mixing
soap
Why are there 2 layers instead of 4?
POLAR substances:
­­Dissolve in H2O
­­Have ionic bonds OR polar bonds
­­Non­symmetrical

NON­POLAR substances:
­­Do not dissolve in H2O
­­Lack a dipole moment (no
) ­­Symmetrical
"Like Dissolves Like"
­­Polar dissolves polar
­­Examples:
*Ionic compounds, sugars, alcohols and H2O
*"Regular" make­up and water­based remover
*"Starch" packing peanuts and H2O

"Like Dissolves Like"
­­Nonpolar dissolves nonpolar
­­Examples:

Soap Molecule
18 C = sodium stearate
"non polar tail"
12 C = sodium lauryl sulfate "polar head"
Soap
(polar)
"Micelle"
(nonpolar)
What part of the soap molecule is attracted to the oil at the center of the structure? To the aqueous solution environment?
