Solubility Curves Day 1

Front

What is a solubility curve?

Back

A graph that shows the relationship between the solubility of a substance and temperature.

Front

Define solubility.

Back

The maximum amount of a solute that can dissolve in a given amount of solvent at a specific temperature.

Front

What is the solubility of K2Cr2O7 in 50 g of water at 90ºC?

Back

35 grams.

Front

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

Back

75 grams.

Front

What is the solubility of KClO3 in 200 g of water at 30ºC?

Back

20 grams.

Front

Which substance is MOST soluble at 0 ºC?

Back

NaNO3.

Front

What does it mean if a solution is unsaturated?

Back

It means that more solute can still be dissolved in the solvent.

Front

What is a saturated solution?

Back

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

Front

What is a supersaturated solution?

Back

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

Front

How does temperature affect solubility?

Back

Generally, solubility increases with temperature for most solids.
