Physical Properties & Solutions

Front

What happens to the solubility of carbon dioxide (CO2) in a liquid as temperature increases?

Back

Higher temperatures decrease the solubility of CO2 in the liquid, causing it to escape from the solution.

Front

How does temperature affect the solubility of oxygen in a bacterial culture?

Back

As temperature increases, the solubility of oxygen in the solution decreases.

Front

What is a method to dissolve crystals back into a solution?

Back

Adding more solvent can help dissolve the crystals back into the solution.

Front

True or False: At different points on a graph, substances can have different amounts of energy.

Back

True.

Front

What will happen when 240 g of KNO3 is added to 100 g of H2O at 40°C?

Back

60 g of KNO3 will dissolve to form a saturated solution, and 180 g will remain undissolved.

Front

Define solubility.

Back

Solubility is the maximum amount of a substance that can dissolve in a given amount of solvent at a specific temperature.

Front

What is a saturated solution?

Back

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

Front

What is the effect of temperature on the solubility of most solids in liquids?

Back

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

Front

What is the relationship between pressure and the solubility of gases in liquids?

Back

Increased pressure increases the solubility of gases in liquids.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more dissolved solute than a saturated solution at the same temperature.
