Solutions and Solubility Curves

Front

What is a solution?

Back

A solution is a homogeneous mixture of two or more substances where one substance (the solute) is dissolved in another (the solvent).

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

Front

What is a solubility curve?

Back

A solubility curve is a graph that shows how the solubility of a substance changes with temperature.

Front

What does it mean if a solution is saturated?

Back

A saturated solution is one that contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is a dilute solution?

Back

A dilute solution is one that has a small amount of solute compared to the amount of solvent.

Front

What is a concentrated solution?

Back

A concentrated solution is one that has a large amount of solute compared to the amount of solvent.

Front

What is the 'Universal Solvent'?

Back

Water is often called the 'Universal Solvent' because it can dissolve many substances.

What happens to the color and taste of a soft drink when it is more diluted?

Back

It becomes lighter in color and weaker in taste.
