yes most likely because you cant separat a solution
The fertilisers can be separated by the process of filteration.
Sometimes is possible, depending on the type of the coloid; for example aerosols.
no as it is desovled in solution you would have to boil off the water.
Yes because filteration would seperate the water from the dirt
An element is an element and can not, in anyway, be separated.
Hand Pricking, sedimentation, decantation, magnetic sepration, filteration, winnowing, sieving.
A gel is an example of a colloid. A colloid cannot be separated in the same way as a suspension can.
nothing
It's considered a solution but it can be separated by evaportaion.
Yes, sugar water is a colloid. A colloid is a mixture in which one substance is dispersed in another, but not dissolved, and sugar particles in water do not completely dissolve but remain suspended in the water.
colloid!
Brass is a solution as it is homogenous in composition. In cannot be separated out. The particles are as one and do not hang where there could be spun out. Since they cannot be separated, brass is a solution.
