(b) An unknown mass of Na3PO4(s) is dissolved in water to form 50.00 mL of solution. This
is Solution A.
Then 10.00 mL of Solution A is diluted with water to 50.00 mL. The final solution is
Solution B.
20.00 mL of Solution B contains 4.408 x 1020 sodium ions.
(NA = 6.022 x 1023 mol-1)

Identify the characteristics of intermolecular interactions including hydrogen bonding, ion-dipole, and the
hydrophobic effect.
A solid line represents a covalent bond and a dotted line represents an intermolecular attraction. Select the image or images
that represent a hydrogen bond.

H-H
-C----H-F-
A water molecule has polar O-H bonds that result in regions of partial pasitive charge (hydrogen atoms) and a region of
partial negative charge (oxygen atom with lone pains). Place the Na* and CI ions where H,0 molecules are properly
oriented to form ion-dipole interactions.
Answer Bank
Select the three true statements.
Forming an ordered network of water around hydrophobic molecules increases the entropy of water.
The tendency of hydrophobic molecules to aggregate in water is called the hydrophobic effect.
Placing a hydrophobic molecule into water causes water molecules to orient themselves around it.
Nonpolar molecules that have no polar groups (e.g. hydrocarbons)…
