Which of the following could you do to increase the rate of dissolution of a solute in a solution?(1 point)

Question

Increase the particle size of the solute because there would be a greater attraction between the solute and solvent particles.

Decrease the particle size of the solute because it would increase how often the solute and solvent particles would collide.

Increase the particle size of the solute because there would be a greater surface area exposed to the solvent.

Decrease the particle size of the solute because the mass of the solute would be greater.

Answer 1

To increase the rate of dissolution of a solute in a solution, the best approach would be to decrease the particle size of the solute because it would increase how often the solute and solvent particles would collide. This option is correct because smaller particles have a larger surface area relative to their volume, which allows for more interactions with solvent molecules, leading to a faster dissolution process.

The other options are incorrect for the following reasons:

• Increasing the particle size of the solute generally decreases the surface area available for dissolution, thus slowing down the rate of dissolution.
• Increasing the particle size for a supposed greater attraction does not logically lead to a faster dissolution, as the surface area decreases.
• Decreasing the particle size due to an increase in mass is irrelevant; mass does not directly affect the rate of dissolution in this context.

So the correct choice is the second statement.
