Solutions and Solubility Curves Honors

Front

What type of intermolecular force exists in CH₄?

Back

London forces.

Front

In an aqueous solution, what is the role of water?

Back

Water is the solvent.

Front

What is the definition of molarity?

Back

Molarity is moles of solute/liters of solution.

Front

At 40 degrees Celsius, which salt can dissolve at a concentration of about 60 g/100 cm³ of water?

Back

Potassium nitrate.

Front

If 50 grams of KBr is dissolved in 100 grams of water at 90°C, what type of solution is formed?

Back

The solution is unsaturated.

Front

What are the two main components of a solution?

Back

Solute and solvent.

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 solubility and temperature for a specific solute.

Front

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

Back

The solubility of most salts increases with temperature.

Front

What is the difference between saturated and unsaturated solutions?

Back

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