Intermolecular Forces and Solubility Worksheet

Question 1

Which type of molecular solvent often mixes well with a polar molecular solute?

1. A polar solvent
2. A metal lattice
3. A solid with no solvent particles
4. A solvent chosen only by color

Question 2

Explain how water molecules can interact with a positive ion in solution.

Question 3

A nonpolar liquid forms a separate layer when mixed with water. Which particle description is consistent with this behavior?

1. The nonpolar molecules become water molecules.
2. Water molecules interact favorably with one another, and the two liquids have limited mutual solubility.
3. Every molecule becomes a free ion.
4. Mixing changes the number of protons in both liquids.

Question 4

Explain why the general mixing rule is insufficient to calculate an exact solubility in grams.

Question 5

Which solute–solvent pair gives the greatest solubility?

1. P in water
2. P in nonpolar solvent
3. Q in water
4. Q in nonpolar solvent

Question 6

How many more grams of Q dissolve per 100 g in the nonpolar solvent than in water?

Write your answer and work on the printable worksheet, or answer online.

Question 7

Which observation supports the idea that a nonpolar solute can mix better with a nonpolar solvent?

1. P has higher solubility in water.
2. Q is more soluble in the nonpolar solvent than in water.
3. Water dissolves equal masses of P and Q.
4. P and Q have equal solubility in both solvents.

Question 8

A student says polar solute P cannot dissolve at all in a nonpolar solvent. Use the table to evaluate the claim.
