Science year 8_ 2.2 Solutions and solubility

What is the process of making solutions with different concentrations called?

• Solubility

• Dilution

• Concentration

• Saturation

Which term describes the ability of a solute to dissolve in a solvent?

• Insoluble

• Solubility

• Saturated

• Concentrated

What is the term for a solution that cannot dissolve any more solute at a given temperature?

• Dilute

• Saturated

• Soluble

• Concentrated

What do you call a solution with a high amount of solute particles?

• Dilute

• Concentrated

• Insoluble

• Soluble

What is a solution?

• A mixture of two solids

• A substance that cannot dissolve

• A mixture where a solute is dissolved in a solvent

• A type of chemical reaction

What is the difference between a concentrated solution and a dilute solution?

• A concentrated solution has fewer solute particles than a dilute solution

• A concentrated solution has more solute particles than a dilute solution

• A concentrated solution has the same number of solute particles as a dilute solution

• A concentrated solution has no solute particles

What equipment is needed to make different concentrations of a solution?

• Safety glasses, test tubes, pipette, measuring cylinders

• Beaker, spoon, thermometer, funnel

• Flask, balance, filter paper, magnet

• Bunsen burner, tripod, gauze, stopwatch

How much water is added to the strong food dye solution to make solution B?

• 5 cm³

• 10 cm³

• 2 cm³

• 8 cm³

What do you notice about the solutions?

• They all have the same concentration.

• They all have different total volumes.

• They all have the same total volume.

• They all have different colors.

How can you tell which is the least concentrated?

• By the color of the solution.

• By the volume of water added.

• By the volume of food dye solution.

• By the total volume of the solution.
