Solubility and Solution Types

The video continues the discussion on solutions, covering unsaturated, saturated, and supersaturated solutions. It explains the differences between these types, using examples like food coloring and sugar in water. The video also discusses how temperature and pressure can create supersaturated solutions, using Coca-Cola as an example.

What is a solution that can dissolve more solute than it currently contains called?

• Saturated solution

• Unsaturated solution

• Supersaturated solution

• Concentrated solution

Which analogy is used to describe a saturated solution?

• A cup of tea

• A balloon

• A sponge full of water

• A dry sponge

What happens when you add more solute to a saturated solution?

• The solute dissolves completely

• The solution becomes unsaturated

• The solution becomes supersaturated

• The excess solute remains undissolved

How can a supersaturated solution be created?

• By stirring continuously

• By changing temperature or pressure

• By diluting the solution

• By adding more solute

What is the role of pressure in creating a supersaturated solution in a can of soda?

• It decreases the solubility of CO2

• It increases the solubility of CO2

• It has no effect on solubility

• It evaporates the CO2

What happens to a supersaturated solution of CO2 when a soda can is opened?

• The solution becomes unsaturated

• The CO2 is released as bubbles

• The CO2 remains dissolved

• The solution becomes more concentrated

Which type of solution is described as holding more solute than it should under normal conditions?

• Dilute solution

• Saturated solution

• Unsaturated solution

• Supersaturated solution

What is the main difference between a saturated and a supersaturated solution?

• Supersaturated solutions are less stable

• Saturated solutions are always under pressure

• Supersaturated solutions are created by manipulating conditions

• Saturated solutions can hold more solute

What is a common example of a supersaturated solution that can be activated by a physical action?

• A chemical cold pack

• A can of soda

• A cup of coffee

• A glass of milk

What happens to the solubility of a solute when the temperature is increased?

• It increases

• It remains the same

• It evaporates

• It decreases
