Understanding Solutions and Solubility

What is the role of a solvent in a solution?

• It is a gas that evaporates quickly.

• It is a mixture of two solids.

• It is the liquid that dissolves the solute.

• It is the solid that gets dissolved.

Which of the following is an example of an insoluble substance in coffee?

• Candle wax

• Milk

• Salt

• Sugar

How does increasing the temperature of a solvent affect the solubility of a solute?

• It decreases the solubility.

• It has no effect on solubility.

• It increases the solubility.

• It makes the solute evaporate.

Why does granulated sugar dissolve faster than a sugar cube?

• It is less dense than a sugar cube.

• It is made of different sugar particles.

• It has a higher surface area to volume ratio.

• It has a lower surface area to volume ratio.

What is the effect of stirring on the dissolving process?

• It slows down the dissolving process.

• It has no effect on the dissolving process.

• It helps the solute to dissolve faster.

• It changes the color of the solution.
