What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.

Front

What is crystallization?

Back

The process where dissolved substances form solid crystals as the solvent evaporates.

Front

What is the relationship between concentration and conductivity in a solution?

Back

As concentration increases, conductivity typically increases due to more charged particles being present.
