Solutions, Molarity, and Molality

What does "like dissolves like" mean?

• Solute and solvent must have different IMFs in order to make a homogenous solution

• Both solute and solvent must have similar IMFs in order to make a homogenous solution

• Both solute and solvent must be the same color in order to make a homogenous solution

• Solutes must be a fine powder and will dissolve in any solvent

Since "like dissolves like", water and oil will not mix because

• both of them are polar

• both of them are nonpolar

• oil is polar and water is nonpolar

• oil is nonpolar and water is polar

The _____ is the thing being dissolved.

• solute

• solvent

What is a solvent?

• The substance that does the dissolving in a solution.

• The substance that is being dissolved in a solution.

• The mixing of different substances.

• The process in which neutral molecules lose or gain electrons.

When no more solute dissolves the solution is _________

• supersaturated

• unsaturated

• saturated

• supercalifragilisticexpialidocious
