Solutions & Solubility

Front

What is a saturated solution?

Back

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

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more dissolved solute than a saturated solution at the same temperature, often achieved by heating and then cooling the solution.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature and pressure.

Front

What happens to a saturated solution when more solute is added?

Back

No additional solute will dissolve; it will remain undissolved.

Front

What is the solubility of NaNO3 in 100 g of water at 10 ºC?

Back

80 grams.

Front

What type of solute is naphthalene?

Back

Naphthalene is a nonpolar solute.

Front

What is the effect of temperature on solubility?

Back

Generally, the solubility of solids in liquids increases with temperature, while the solubility of gases decreases.

Front

What is the difference between solute and solvent?

Back

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

Front

What is a solution?

Back

A solution is a homogeneous mixture of two or more substances.

Front

What is the role of agitation in dissolving a solute?

Back

Agitation increases the rate of dissolving by helping to disperse the solute particles throughout the solvent.
