Why does reducing solute particle size increase the speed at which the solute dissolves in water answers?
A third factor that affects the rate of dissolving is the size of solute particles. For a given amount of solute, smaller particles have greater surface area. With greater surface area, there can be more contact between particles of solute and solvent.
Why does heating increase the speed at which a solute dissolves in water?
Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.
What is the particle size of solute in solution?
The size of solute particles in the solutions is extremely small. It is less than 1 nm in diameter. The particles of a solution cannot be seen even with a microscope.
How does the size of the solute affect its solubility?
Size of the particles — When a solute dissolves, the action takes place only at the surface of each particle. When 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 rate of solution.
What is the size of solute particles in collides?

Does the size of the salt affects how fast it dissolves in water?
What is the effect of size of particle?
The particle size of a solid controls the surface area available for interactions between aqueous solution and the solid body. Larger surface area per mass or volume normally promotes rapid reaction, thus resulting in higher leached concentrations.
