• Solvent

• Solution

• Miscibility

Which of the following would be the MOST soluble in water?

• CH₄

• CO₂

• NH₃

When two liquids have very different polarity, they are _________________________ in each other.

• miscible

• immiscible

Many ionic compounds dissolve in water because

• ionic compounds have weak intermolecular forces

• water is highly polar

• water can dissolve all solutes

What statement best describes the solubility of this molecule?

• it is completely insoluble in water because of the large nonpolar segment of the molecule

• a small amount of it can dissolve in water because of the OH group at the end of the molecule.

• it is highly soluble in water because water is the universal solvent.
