Particle Size in Suspension, True Solution and Colloidal Solution

Suspension, true solution, and colloidal solution are different types of mixtures, each with varying particle sizes. The size of particles in suspension, true solution, and colloidal solution varies in the order:

Suspension > Colloidal > True Solution

Let's understand this order in detail:

Suspension
- A suspension is a mixture in which particles are suspended in a liquid or gas but are too large to stay uniformly distributed.
- The particles in a suspension are visible to the naked eye and settle down when left undisturbed.
- The particle size in a suspension is typically greater than 1000 nanometers (nm), which is considered to be macroscopic.
- Examples of suspension include muddy water, blood, and sand in water.

Colloidal Solution
- A colloidal solution is a mixture in which the particle size is intermediate between that of a true solution and a suspension.
- The particles in a colloidal solution are too small to be seen by the naked eye but are large enough to scatter light, making the solution appear hazy or opaque.
- The particle size in a colloidal solution is typically between 1 and 1000 nm.
- Examples of colloidal solutions include milk, ink, and blood plasma.

True Solution
- A true solution is a homogeneous mixture in which the particles are so small that they cannot be seen by the naked eye or even by a microscope.
- The particles in a true solution are molecules or ions that are evenly dispersed throughout the solvent.
- The particle size in a true solution is typically less than 1 nm.
- Examples of true solutions include sugar dissolved in water and salt dissolved in water.

Conclusion
In summary, the size of particles in suspension, true solution, and colloidal solution varies in the order: suspension > colloidal > true solution. This order is based on the particle size, with suspensions having the largest particles and true solutions having the smallest particles.
