Question

1. choose the best answer.

____ affects dissolution because dissolution takes place on the surface of a solute.
temperature
stirring/agitation
pressure
size of the solid

Explanation:

The size of the solid affects the surface - area to volume ratio. A smaller - sized solid has a larger surface area exposed to the solvent, which speeds up the dissolution process as dissolution occurs on the surface of the solute. Temperature affects the kinetic energy of particles, stirring/agitation helps in distributing dissolved particles, and pressure mainly affects the dissolution of gases.

Answer:

Size of the solid
