A homogeneous solution doesn't settle.
Yes, a solution can settle over time. This settling process occurs as the particles in the solution separate and sediment to the bottom due to gravity. To prevent settling, the solution can be continuously stirred or shaken.
Supersaturated
sand
solution, ........ but with a bit of particles in suspension,
The difficulty that arises when the precipitate is not allowed to settle completely from solution is that the precipitate will not be as pure as it could be. If the precipitate is not allowed to settle, impurities will remain in the solution and will be present in the precipitate. This will result in a less pure product.
I'm pretty sure that would be a colloid. Hope that helps!
saturated solution
solution
observe that the particles in a solution are uniformly distributed and do not settle over time, while the particles in a suspension settle out and form a distinct layer.
Salt water is a solution, not a colloid suspension. In a solution, the solute particles are dissolved on a molecular level and do not settle out. Colloid suspensions, on the other hand, have larger solute particles that do not dissolve and may eventually settle out.
milk is a colloid, and not a solution. the particles of casein do not settle out after standing.
It is Precipitation
