What can particles in solution NOT do because ther are so small
They don't precipitate but I doubt that is what you are looking for.
Particles in a solution, such as molecules or ions, exhibit different behaviors compared to larger objects due to their small size. Here are a few things that particles in a solution cannot do or have limitations on:
1. Being filtered: Small particles in a solution, like molecules or ions, cannot be filtered using conventional methods. This is because the filter pores are often larger than the particles themselves, allowing them to pass through.
2. Sedimentation: Due to their small size, particles in a solution take a longer time to settle down under the force of gravity. While larger particles settle quickly, smaller particles may stay suspended in the solution for an extended period, causing the solution to appear cloudy or turbid.
3. Settling in layers: In a heterogeneous solution where particles differ in size or density, they do not settle in distinct layers. Instead, smaller particles tend to remain dispersed throughout the solution and might move randomly due to the continuous collisions with other particles.
4. Separation by gravitational methods: Particles in solution cannot be easily separated through gravitational methods like decanting. Since their settling rate is slow, it would take a considerable amount of time for particles to settle completely, making it inefficient for separation.
To study or manipulate particles in solution, techniques such as centrifugation, filtration based on specific sizes, or precipitation reactions can be employed to overcome the limitations posed by their small size. These methods help researchers isolate and analyze particles based on their properties or characteristics.
