As an expert in the field of physical chemistry, I can provide you with a detailed explanation of how light interacts with different states of matter, specifically focusing on the concept of a suspension.
Light, being an electromagnetic wave, can interact with matter in various ways, including absorption, reflection, refraction, and scattering. When we talk about light passing through a suspension, we are essentially discussing the optical properties of a heterogeneous mixture where the particles are dispersed throughout a fluid but are not dissolved.
A suspension is characterized by particles that are larger than those found in a solution and are typically in the range of 1 micrometer to 1 millimeter in size. These particles are large enough to scatter light, which means that when light passes through a suspension, it can be scattered in different directions. This scattering of light is what causes the turbid or cloudy appearance of a suspension.
The degree to which light can pass through a suspension depends on several factors:
1. Particle Size: Larger particles scatter light more effectively, reducing the amount of light that can pass through the suspension.
2. Concentration of Particles: The more particles present in the suspension, the more light is scattered, and the less transparent the suspension becomes.
3. Wavelength of Light: Shorter wavelengths of light (such as blue and violet) are scattered more than longer wavelengths (such as red and yellow). This is why the sky appears blue during the day.
4. Refractive Index: The difference in refractive index between the particles and the suspending medium affects how much light is scattered. A larger difference results in more scattering.
5. Polarization of Light: The orientation of light waves can also influence how they interact with the particles in a suspension.
Now, let's compare this with a solution and a colloid. A solution is a homogeneous mixture where the solute particles are dissolved at the molecular or ionic level, typically smaller than 1 nanometer. These particles are too small to scatter light significantly, so light can pass through a solution with minimal scattering, making it transparent.
A colloid, on the other hand, is an intermediate state between a solution and a suspension. Colloidal particles are larger than those in a solution but smaller than those in a suspension, usually ranging from 1 nanometer to 1 micrometer. Some colloids can scatter light, but the scattering is less pronounced than in a suspension, and the mixture can appear translucent or semi-transparent.
In summary, light can pass through a suspension, but its passage is significantly hindered by the scattering caused by the larger particles present. The optical properties of a suspension are quite distinct from those of a solution or a colloid, with the latter two allowing light to pass through with minimal scattering due to the smaller size of their dispersed particles.

In summary: A solution is always transparent, light passes through with no scattering from solute particles which are molecule in size. The solution is homogeneous and does not settle out. ... A colloid is intermediate between a solution and a suspension.
