Reading Solubility Curves

Front

What is a solubility curve?

Back

A graphical representation showing the relationship between the solubility of a substance and temperature.

Front

What does it mean if a solution is saturated?

Back

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

Front

What does it mean if a solution is unsaturated?

Back

An unsaturated solution can still dissolve more solute at a given temperature.

Front

What does it mean if a solution is supersaturated?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature, often achieved by heating.

Front

How can you determine the most soluble compound at a specific temperature using a solubility curve?

Back

By locating the point on the curve corresponding to the temperature and comparing the solubility values of different compounds.

Front

How can you determine the least soluble compound at a specific temperature using a solubility curve?

Back

By identifying the lowest point on the curve at the given temperature for the compounds in question.

Front

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

Back

The solubility of most salts increases with an increase in temperature.

Front

What happens to the solubility of gases as temperature increases?

Back

The solubility of gases typically decreases as temperature increases.

Front

What is the significance of the intersection point on a solubility curve?

Back

The intersection point indicates the solubility of two different compounds at the same temperature.

Front

How do you read a solubility curve?

Back

Find the temperature on the x-axis, then move vertically to find the solubility of the compound on the y-axis.
