Mixtures, Solutions & Solubility Curves

Front

What is a mixture?

Back

A combination of two or more substances that are not chemically bonded and can be separated by physical means.

Front

What is a solution?

Back

A homogeneous mixture where one substance (solute) is dissolved in another (solvent).

Front

Define solubility.

Back

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

Front

What happens to solubility as temperature increases?

Back

Generally, solubility increases for most solids as temperature increases.

Front

What is a solubility curve?

Back

A graph that shows the relationship between solubility and temperature for a specific solute.

Front

What does it mean if a solute is 'least soluble'?

Back

It means that the solute dissolves in the solvent to the smallest extent compared to other solutes.

Front

What is the effect of temperature on the kinetic energy of particles?

Back

Increasing temperature increases the kinetic energy of particles, leading to more frequent and energetic collisions.

Front

What is the difference between a solution and a mixture?

Back

A solution is a homogeneous mixture where the solute is completely dissolved, while a mixture can be heterogeneous and the components can be physically separated.

Front

What is an example of a solute?

Back

Salt (sodium chloride) when dissolved in water.

Front

What is an example of a solvent?

Back

Water is often referred to as the universal solvent because it can dissolve many substances.
