Lesson details
Lesson outcome
I can use the particle model to explain both how solutions form and how solutions differ from a suspension.
Show transcript
Suspensions are not solutions, as solid particles can be seen, and eventually will settle over time.
Forces of attraction between solute particles have to be overcome for something to dissolve.
In a mixture, one particle may fit into spaces between another type, making the total volume less than expected.
Not every substance can be dissolved (is soluble) in a solvent.
Dissolving is not the same as melting, but both are physical processes.
