Answer to Question #166316 in General Chemistry for Phyroe

Question

The grinding of a large crystal of a substance into smaller crystals increases the rate of solution of the substance. Why?

Answer 1

Because dissolving occurs at the surface of a crystal, the more solute surfaces that are exposed to solvent, the faster the solute will dissolve. ... The surface area is increased, for example, by grinding up one large crystal into many small crystals or granules.
