What is a saturated solution?

Back

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

Front

Which unit is NOT used to express concentration?

Back

Density is not a unit used to express concentration.

How many grams of K2Cr2O7 are soluble in 100 g of water at 95 ºC?

Back

75 grams of K2Cr2O7 are soluble in 100 g of water at 95 ºC.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature.

Front

How can a solution become supersaturated?

Back

A solution can become supersaturated by heating it to dissolve more solute and then allowing it to cool.

Front

What factors affect the solubility of a solute in a solvent?

Back

Factors include temperature, pressure, and the nature of the solute and solvent.

Front

What is the definition of concentration in a solution?

Back

Concentration is the amount of solute present in a given quantity of solvent or solution.

Front

What is the difference between a saturated and an unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve, while an unsaturated solution can still dissolve more solute.

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases as temperature increases.

Front

What is the role of temperature in the solubility of gases?

Back

The solubility of gases typically decreases as temperature increases.
