Why does crushing help a solid solute dissolve?
The rate of dissolution of a solid is dependent on the surface area reaction. By crushing the cube, the surface area is greatly increased, thus increasing the rate of dissolution.
What effect does crushing have on solution rate?
Crushing sugar into smaller particulates INCREASES the rate at which the sugar will dissolve because the water can act on a larger overall surface area.

A solution in crystallizing rate of the solute equals the dissolving rate of the solute must be?
saturated
How does agitation afect the rate of dissolving?
It increases the rate at which the solute dissolves.
How does stirring affect the rate at which a material dissolves in a solution?
Stirring increases solution ratestirring brings fresh parts of the solvent into contact with the solute and particles are forced to connect. (http://en.wikipedia.org/wiki/Rate_of_solution)
Why does shaking affect the rate at which the solute dissolves?
Shaking affects the rate at which a solute dissolves because it increases the molecular activity of the solute within the solvent. When the molecular activity is increased, the rate of dissolving is also increased.
What statement is true for a saturated solution?
The rate of crystallizing is equivalent to the rate of dissolving.
Increasing the surface area between solute and solvent increases what?
Will increase the rate of dissolution and hence how fast the solute is dissolved.
What happen when solvent is equal to solute?
solution is in equilibrium and the solvent and solute continue diffusion or osmosis at an equal rate.
3 ways to increase the rate of solvation?
1. Stir or shake the solution 2. Expose more surface by crushing a solid solute. 3. Warm the solution.
What does shaking a solution do to the rate of dissolving?
The mixing between solute and solvent is improved.
