So we got the knowledge that Colloids are 'molecular' aggregates ,,, but from our perspective,, it is a particle!!! like a grain of salt... as a visual,,, we might think of the cinder blocks as being a molecular aggregate(colloid) and then think of peds
as particle aggregate or colloid aggregate or cinder block aggregate...
If you are able to think in terms of building blocks,,, all we are talking about here is starting with smallest to largest... Don't overthink it...
The term aggregate
is a loaded term,,, that from the common sense perspective,,, means group or buch,,, in our current day vernacular...
So, for soils a group of molecular aggregates that color="blue"] cohere,
[/color] to one another to form larger aggregates allow more pore space for water to move...
Are we on the same page yet???
No, we clearly are not. Take your own advice, note the definition which clearly states a colloid MAY
be a molecular aggregate, not IS
one as you have incorrectly stated.
Further, please understand what in solution
means before you use the terms, particularly since you have used them incorrectly here. A suspended solid is not in solution
nor does it precipitate
out of solution, it settles.
And finally, more education is again in order.
