what are the difference between true solution and suspension? (DAV2022...
A true solution is a homogeneous mixture of two or more substances, where the particles of the solute are dissolved in the solvent and are uniformly distributed throughout the solution. A suspension is a heterogeneous mixture of two or more substances, where the particles of the solute are suspended in the solvent and are not uniformly distributed throughout the mixture.
There are several key differences between true solutions and suspensions:
1. Particle size: In a true solution, the particles of the solute are very small and are evenly distributed throughout the solution. In a suspension, the particles of the solute are larger and are not evenly distributed throughout the mixture.
2. Transparency: True solutions are transparent, while suspensions are often cloudy or opaque.
3. Filtering: True solutions can be easily filtered through a filter paper, while suspensions cannot be filtered and will leave a residue on the filter paper.
4. Separation of particles: The particles in a true solution cannot be separated by physical means, while the particles in a suspension can be separated by physical means such as sedimentation or decantation.
5. Stability: True solutions are stable, while suspensions are often unstable and will separate over time.
True solutions and suspensions are both types of mixtures, but they have different physical properties and behave differently. Understanding the differences between true solutions and suspensions is important in fields such as chemistry, physics, and biology.
