Question

which would not increase the rate of dissolution? ice agitation heat small particle size

Explanation:

To determine which does not increase the rate of dissolution, we analyze each option:

• Agitation: Stirring or agitating a solution increases the rate of dissolution by bringing fresh solvent into contact with the solute.
• Heat: Increasing temperature (adding heat) generally increases the rate of dissolution as it provides more energy for solute particles to break apart and mix with the solvent.
• Small Particle Size: Smaller particle size increases the surface area of the solute exposed to the solvent, leading to a faster dissolution rate.
• Ice: Adding ice (lowering temperature) typically decreases the rate of dissolution because lower temperatures reduce the kinetic energy of molecules, slowing down the dissolving process. So ice would NOT increase the rate of dissolution.

Answer:

A. Ice
