They cannot be separated by the process of filtration . But they can be separated by centrifugation technique

Explanation:

Homogeneous and Heterogeneous:
- A homogeneous mixture is a mixture that has a uniform composition throughout, meaning that the components are evenly distributed and cannot be visibly distinguished.
- A heterogeneous mixture is a mixture that has a non-uniform composition, meaning that the components are not evenly distributed and can be visibly distinguished.

True Solutions:
- True solutions are homogeneous in nature.
- The solute particles in a true solution are so small that they cannot be seen with the naked eye or even with a microscope.
- The solute particles are evenly distributed throughout the solvent, resulting in a uniform composition.

Suspensions:
- Suspensions are heterogeneous in nature.
- In a suspension, the solute particles are much larger than the particles in a true solution.
- These particles are not evenly distributed and can be seen with the naked eye.
- Over time, the solute particles will settle at the bottom of the mixture, requiring the suspension to be shaken or stirred to redistribute the particles.

Colloidal Solutions:
- Colloidal solutions are also heterogeneous in nature.
- The solute particles in a colloidal solution are larger than the particles in a true solution but smaller than the particles in a suspension.
- These particles are dispersed throughout the solvent but are not evenly distributed.
- Unlike true solutions, the solute particles in a colloidal solution can scatter light, making the solution appear cloudy or opaque.

Filtration:
- Filtration is a process used to separate solid particles from a liquid or gas by passing it through a filter medium.
- Filtration can be used to separate suspensions and colloidal solutions from true solutions.
- However, it is not effective in separating solute particles in a colloidal solution because the particles are too small to be retained by a filter.
- Colloidal particles can pass through the filter, resulting in a solution that still contains the solute particles.

Conclusion:
The statement "Solute particles in a colloidal solution can be separated by filtration" is not true because filtration is not an effective method for separating solute particles in a colloidal solution.
