Surface area and solubility

WebWhen the total surface area of the solute particles is increased, the solute dissolves more rapidly. Breaking a solute into smaller pieces increases its surface area and increases its … WebBecause the powder has a larger surface area than the crystal, more of the ions in the salt are exposed to the solvent at any given time, causing them to dissolve more quickly. It should be noted that breaking a solute into smaller pieces doesn't change how much of it will dissolve, it only changes how quickly it will dissolve. Pressure
