Properties of Solutions Flashcard

Front

What is the effect of increasing the temperature of water on the dissolution rate of a sugar cube?

Back

Increasing the temperature of the water increases the dissolution rate of the sugar cube.

Front

What is the effect of decreasing the temperature of water on the dissolution rate of a sugar cube?

Back

Decreasing the temperature of the water decreases the dissolution rate of the sugar cube.

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 happens to a saturated solution when the temperature decreases?

Back

When the temperature decreases, a saturated solution may become supersaturated, leading to crystallization of the solute.

Front

What is the definition of a supersaturated solution?

Back

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

Front

What is the role of hydrogen bonding in water's properties?

Back

Hydrogen bonding in water leads to higher boiling and melting points, and stronger intermolecular attractions.

Front

How does the size of a water molecule compare to that of an ammonia molecule?

Back

The water molecule (H2O) is smaller than the ammonia molecule (NH3), but water has stronger hydrogen bonding.

Front

What is the significance of intermolecular attractions in solutions?

Back

Intermolecular attractions determine the solubility and physical properties of solutions.

Front

What is the relationship between solubility and temperature?

Back

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

Front

What is the definition of dissolution?

Back

Dissolution is the process by which a solute dissolves in a solvent to form a solution.
