Is the substance being dissolved a solute or solvent?

• Solute

• Solvent

• colloid

• suspension

solids INCREASE in solubility as temperature increases.

• True
• False

Gases DECREASE in solubility as temperature increase

• True
• False

What is the substance that dissolves a substance?

• Solvent

• Solute

How does increasing surface area impact the rate of solvation (dissolving)?

• The greater surface area will expose more solute particles to the solvent, leading to faster dissolution.

• An increased surface area will decrease the rate of solvation because the particles are unable to be exposed.

• The increase in surface area has no impact on the rate of solvation.

• A greater surface area will speed up and then slow down the rate of solvation.

How can agitation affect the rate a solute dissolves?

• Agitation can increase the rate a solute dissolves because it can change the temperature, and the change in temperature can impact the rate of solvation.

• Agitation can decrease the rate at which a solute dissolves because the constant motion of stirring will separate the solute particles from the solvent.

• Agitation will increase the rate at which a solute dissolves because, the constant motion of moving will allow fresh solvent to come in contact with the solute particles.

• Agitation can decrease the rate at which a solute dissolves because it will cause the particles of the solute to sink.

How does heat affect the rate a solute dissolves? Why?

• Heating can increase the rate a solute dissolves because the higher temperatures can increase the kinetic energy of the solvent molecules. This causes the solvent particles to move faster and more frequently with the solute.

• It can decrease the rate of a solute because it cause the molecules of the solvent to stick together and not be able to mix with the solute.

• Heat makes the solute molecules bigger, so they dissolve faster and increase the rate of solvation.
