Solubility curve

Front

What is a solubility curve?

Back

A graph that shows 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 is an unsaturated solution?

Back

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

Front

What is a supersaturated solution?

Back

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

Front

At what temperature is KI most soluble according to the solubility curve?

Back

At 10 °C.

Front

Which solute is least soluble at high temperatures?

Back

SO₂ is least soluble at 90 °C.

Front

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

Back

The solubility of most solids increases with temperature.

Front

What happens to the solubility of gases as temperature increases?

Back

The solubility of gases generally decreases as temperature increases.

Front

What is the solubility of NaNO₃ at 0 °C?

Back

NaNO₃ is the most soluble at 0 °C.

Front

How can you describe a solution with 20 grams of KNO₃ dissolved in 100 grams of water at 80 °C?

Back

The solution is unsaturated.
