Answer (1)
Answer:In chemistry, colloids, suspensions, and solutions are different types of mixtures, distinguished by the size of the particles dispersed within them.A colloid is a heterogeneous mixture with particles larger than those in a solution but smaller than those in a suspension, generally ranging from 1 to 1000 nm in diameter. These particles are dispersed evenly throughout the substance and do not settle out. Colloids often appear cloudy or opaque and exhibit the Tyndall effect, meaning they scatter light, making the light beam visible when shone through them (like light through fog). Examples include milk, fog, and gelatin.A suspension is a heterogeneous mixture containing solid particles that are large enough to be seen with the naked eye and will eventually settle out if left undisturbed. The particles in a suspension are typically larger than 1000 nm. Examples include muddy water, sand in water, or chalk in water.A solution is a homogeneous mixture where one substance (the solute) is completely dissolved in another (the solvent), resulting in a single phase that appears clear. The particles in a solution are extremely small, typically less than 1 nanometer (nm) in diameter, meaning they cannot be seen even with a microscope and will not settle out over time. Examples include sugar dissolved in water or salt water.
