Interpreting 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 for a solution to be saturated?

Back

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

Front

How does temperature affect solubility?

Back

Generally, increasing temperature increases the solubility of solids in liquids, while the effect on gases can vary.

Front

What is the solubility of KNO3 at 40 degrees Celsius?

Back

65 grams per 100 mL of water.

Front

Which solute is most likely a gas?

Back

Ce2(SO4)3 is most likely a gas compared to the other options.

Front

At what temperature can you fully dissolve 60g of KNO3?

Back

37 ºC.

Front

How much more NaCl can be dissolved in 100 mL of water at 60 ºC to reach saturation?

Back

15 grams.

Front

What is the effect of decreasing temperature on the solubility of most solids?

Back

Decreasing temperature usually decreases the solubility of most solids.

Front

What is the solubility of NaNO3 at 60 degrees Celsius?

Back

Approximately 90 grams per 100 mL of water.

Front

What is the significance of a solubility curve in chemistry?

Back

It helps predict how much solute can dissolve at different temperatures.
