why does 1 g of finely ground salt dissolve in water faster than an equal mass of coarsely ground salt?\na. the finely ground salt is less dense than the coarsely ground salt.\nb. the finely ground salt contains fewer particles than the coarsely ground salt.\nc. the finely ground salt has a larger surface area than the coarsely ground salt.\nd. the finely ground salt has a different chemical nature than the coarsely ground salt.

Answer

Brief Explanations:

The rate of dissolution depends on the surface - area available for interaction with the solvent. Finely ground salt has smaller particles, resulting in a larger total surface - area compared to coarsely ground salt of the same mass. This allows more salt particles to come into contact with water molecules simultaneously, speeding up the dissolution process.

Answer:

C. The finely ground salt has a larger surface area than the coarsely ground salt.
