Solubility Curves

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 substance is soluble?

Back

It means that the substance can dissolve in a solvent, such as water, to form a solution.

Front

Which substance has the slowest increase in solubility with temperature: SO₂, NaCl, KCl, or KNO₃?

Back

NaCl.

Front

What happens to the solubility of Ce₂(SO₄)₃ from 0°C to 100°C?

Back

Back

70 grams.

Front

What is the solubility of Ce₂(SO₄)₃ at 80°C in 100 g of H₂O?

Back

Front

What is the effect of temperature on the solubility of most solid solutes?

Back

Generally, the solubility of most solid solutes increases with an increase in temperature.

Front

What is a saturated solution?

Back

A solution in which no more solute can dissolve at a given temperature.

Front

What is the significance of a solubility graph?

Back

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