What is the effect of making smaller particles of a solid solute on the rate of dissolving?
Answer and explanation
Correct answer: Rate of dissolving may increase
Breaking a solid into smaller particles increases its total surface area for the same mass. More solute surface then contacts the solvent, so dissolving can occur faster. However, particle size usually changes the rate, not the equilibrium solubility itself. Thus A is correct; the other options describe impossible effects.
