The solution and melting processes are the same.

Illustrated by the conversation, "Are you going out? It's raining very hard." "Don't worry, I won't melt."

It doesn't matter whether a liter of solution or 1000 g of solvent are used in calculations.

Because molarity and molality are very similar in dilute aqueous solutions, students often assume this statement is true. To avoid this, use solutions with densities quite different from 1.0 g/mL.

All liquids are solutions.

While it is very difficult to get anything to be "pure," most liquids are much less good as solvents than water, In the same way that we can speak of pure water, we can speak of pure liquids.

Soluble and insoluble.

Materials that are insoluble almost always dissolve at least a little bit.

Hydration means the attachment of any solvent molecules to solute molecules.

Hydration is the term used when the solvent is water. Solvation is used to describe the general case of a solute interacting with solvent.

Solutions are not just solids and liquids.

In a sense, any gas consisting of more that one substance (such as air) is a solution. The distinction between gaseous and other solutions is that, in gases, there is no solvation.

Like always dissolves like.

This is a generalization. Acetic acid dissolves in water, but also in benzene and carbon tetrachloride.

The solubility of a solid in a liquid increases with increase in temperature.

Not always true. Sodium sulfite, calcium acetate, and lithium sulfate are exceptions.

Insoluble compounds do not dissolve.

All ionic compounds dissolve to some extent in water.
