SolutionDefinition: A solution is a homogeneous mixture where the solute is completely dissolved in the solvent.Particle Size: Less than 1 nanometer (nm), making the particles too small to be seen with the naked eye.Appearance: Clear and transparent due to the small particle size.Settling of Particles: Particles do not settle over time.Filtration: Cannot be separated by filtration.Tyndall Effect: Does not exhibit the Tyndall effect (no scattering of light).Examples: Saltwater, sugar solution, vinegar.2. SuspensionDefinition: A heterogeneous mixture where solid particles do not dissolve and are visible.Particle Size: Greater than 1000 nanometers (nm), with large, visible particles.Appearance: Cloudy and opaque because the particles are not dissolved.Settling of Particles: Particles settle when left undisturbed.Filtration: Can be separated by ordinary filtration.Tyndall Effect: Strongly exhibits the Tyndall effect (scatters light visibly).Examples: Muddy water, sand in water, flour in water.3. ColloidDefinition: A heterogeneous mixture where fine particles are dispersed throughout but do not settle easily.Particle Size: Between 1 nanometer and 1000 nanometers (nm), larger than a solution but smaller than a suspension.Appearance: Cloudy but uniform; particles are too small to be seen individually.Settling of Particles: Particles do not settle over time.Filtration: Cannot be separated by ordinary filtration.Tyndall Effect: Exhibits the Tyndall effect, causing light to scatter.Examples: Milk, mayonnaise, jelly, fog.
