What can you add to make a solution more concentrated?

Back

You can make a solution more concentrated by adding solute.

Front

How would you classify a KBr solution with a concentration of 90 g/100 g of water at 50°C?

Back

The solution is classified as supersaturated.

Front

What is a saturated solution?

Back

A saturated solution is one that contains the maximum amount of solute that can dissolve at a given temperature and pressure.

Front

What is the effect of temperature on solubility of solids in liquids?

Back

Generally, increasing temperature increases the solubility of solids in liquids.

Front

What is the definition of solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is the definition of solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution.

Front

What is a dilute solution?

Back

A dilute solution is one that contains a small amount of solute relative to the amount of solvent.
