Front

What happens to the molarity of a solution when more solvent is added?

Back

The molarity decreases.

Front

What is the term for a mixture with more solute dissolved in the solvent than is usually soluble?

Back

Supersaturated.

Front

How do you calculate the molarity of a solution?

Back

Molarity (M) = moles of solute / liters of solution.

Front

If you dilute a solution, what happens to its concentration?

Back

The concentration decreases.

Front

What is the molarity of a solution if 1.1 moles of solute are dissolved in 3.5 liters of solution?

Back

0.31 M.

Front

How many moles of solute are in a 2.0 M solution if the volume is 3 liters?

Back

6.0 moles.

Front

What is a saturated solution?

Back

A solution that contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is the effect of temperature on solubility?

Back

Generally, solubility increases with temperature for solids and decreases for gases.

Front

What is the definition of a concentrated solution?

Back

A solution that contains a large amount of solute relative to the amount of solvent.

Front

What is dilution in the context of solutions?

Back

Dilution is the process of reducing the concentration of a solute in a solution, usually by adding more solvent.
