Understand the concept of passive diffusion: Passive diffusion is the movement of particles from an area of higher concentration to an area of lower concentration without the use of energy.
Visualize the concentration gradient: Imagine a solution where particles are unevenly distributed, with more particles in one area than another.
Recognize the driving force: The movement is driven by the concentration gradient, where particles naturally move to balance the concentration throughout the solution.
Consider the random motion of particles: Particles are constantly moving in random directions, but the net movement is towards the area of lower concentration.
Apply the concept to the problem: Based on the principles of passive diffusion, particles in a solution move from an area of higher concentration to an area of lower concentration.
