Solutions and Solubility Curves

Front

What effect does increasing temperature have on the kinetic energy of particles in a solution?

Back

Increasing the temperature increases the kinetic energy of particles, leading to more frequent collisions between them.

Front

What is an example of a solution?

Back

Salt water is an example of a solution.

Front

At what temperature can you fully dissolve 140g of NaNO3?

Back

140g of NaNO3 can be fully dissolved at 73°C.

Front

Which solute is least soluble at 90°C?

Back

Solid C is the least soluble at 90°C.

Front

What type of solution is formed when 60g of NaNO3 is dissolved in 100g of H2O at 40°C?

Back

The solution is unsaturated.

Front

Define solubility.

Back

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

Front

What is a solubility curve?

Back

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

Front

How does pressure affect the solubility of gases in liquids?

Back

Increasing pressure increases the solubility of gases in liquids.

Front

What is the difference between a saturated and an unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.

Front

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

Back

The solubility of most solids increases as temperature increases.
