Question

Question 5 why does grinding solid crystals increase the rate of dissolving for a solid solute in water? smaller crystals are more polar. smaller crystals are more nonpolar. smaller crystals have more energy. smaller crystals have more surface area. none of the above

Answer 1

Grinding solid crystals increase the rate of dissolving for a solid solute in water because smaller crystals have more surface area. The solubility of a substance depends on the physical and chemical properties of the solute and solvent as well as the temperature, pressure and the pH of the solution. For example increase in temperature increases the rate at which a solute dissolves in a solvent.
