Back

A concentrated solution has a high amount of solute compared to the solvent, such as a strong saltwater solution.

Front

What is the role of stirring in dissolving a solute?

Back

Stirring helps distribute the solute particles throughout the solvent, increasing the interaction and speeding up the dissolving process.

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature and pressure.
