Solutes and Dissolution: Video Review

What does the "rate of dissolving" refer to?

• The total amount of solute that can dissolve.

• How quickly a solute dissolves in a solvent.

• The temperature at which a solute dissolves.

• The type of chemical bonds in the solute.

Which of the following is a factor that influences the rate of dissolving?

• The color of the solvent.

• The shape of the container.

• The temperature of the solution.

• The brand of the solute.

If you compare a sugar cube and an equal amount of granulated sugar, which will dissolve faster in water?

• The sugar cube.

• The granulated sugar.

• They will dissolve at the same rate.

• It depends on the type of water.

Why does increasing the surface area of a solute lead to a faster rate of dissolving?

• It makes the solvent molecules move faster.

• More of the solute is exposed to the solvent for interaction.

• It changes the chemical composition of the solute.

• It reduces the density of the solute.

What happens to the dissolving rate when a solute is broken into smaller pieces?

• It decreases because there is less material.

• It increases due to a larger surface area exposed to the solvent.

• It remains the same as the total amount of solute hasn't changed.

• It decreases because the smaller pieces are harder for the solvent to interact with.

Why does stirring a solution increase the rate of dissolving?

• It increases the temperature of the solvent.

• It breaks the solute into smaller pieces.

• It moves occupied solvent molecules away and brings fresh solvent into contact with the solute.

• It makes the solute particles heavier, causing them to sink faster.

How does increasing the temperature of a solvent affect the dissolving process?

• It decreases the kinetic energy of solvent particles, slowing down dissolving.

• It causes solvent particles to move faster, bumping into solute more often and with more force.

• It only affects the amount of solute that can dissolve, not the speed.

• It makes the solute particles less dense, causing them to float.

Which of the following factors generally increases the rate at which a solute dissolves in a solvent?

• Decreasing the surface area of the solute.

• Reducing the temperature of the solvent.

• Stirring the solution.

• Using a larger, single piece of solute.
