Final answer:
A solution is a clear and transparent mixture, like saltwater. A colloid is a mixture where dispersed particles do not settle, like milk. A suspension is a mixture where solid particles are suspended in a liquid or gas and eventually settle, like mud.
Step-by-step explanation:
A solution is a homogeneous mixture where the solute particles are dissolved in the solvent particles, creating a clear and transparent mixture. An example is saltwater, where the salt particles are dissolved in water. On the other hand, a colloid is a heterogeneous mixture where the dispersed particles are distributed throughout the dispersion medium and do not settle. An example is milk, where the fat droplets are dispersed in the liquid. Lastly, a suspension is a heterogeneous mixture where the solid particles are suspended in a liquid or gas and eventually settle over time. An example is mud, where the soil particles are suspended in water.
