Key Characteristics:
* Heterogeneous: The mixture is not uniform throughout, meaning the solid particles are visible and can settle over time.
* Solid particles: These particles are larger than those found in solutions and can be seen with the naked eye or under a microscope.
* Liquid medium: The solid particles are dispersed in a liquid, like water or oil.
* Settling: Gravity causes the solid particles to settle to the bottom of the container over time.
* Easily separated: The solid particles can be separated from the liquid through techniques like filtration or sedimentation.
Examples of Suspensions:
* Muddy water: Soil particles are suspended in water.
* Sand in water: Sand grains are dispersed in water.
* Milk of magnesia: Magnesium hydroxide particles are suspended in water.
* Paint: Pigment particles are suspended in a liquid medium.
How Suspensions Differ from Solutions and Colloids:
* Solutions: The solute (the substance being dissolved) is completely dissolved in the solvent, forming a homogeneous mixture.
* Colloids: The dispersed particles are smaller than in suspensions but larger than in solutions, creating a homogeneous mixture that can scatter light (Tyndall effect).
In summary: A suspension is a heterogeneous mixture of solid particles dispersed in a liquid where the particles are large enough to settle over time and can be easily separated.
