What is the difference between colloids, suspension and true solution?

Answer 1

Well, a solution is #"homogeneous.........."#

And in an #"homogeneous solution"#, all its components are in the same phase. Consider sugar/salt in water, or dinitrogen or dioxygen in the air we breathe. Both are examples of solutions........

On the other hand, #"a suspension"# is #"inhomogeneous"#. Typically this is a slurry of finely divided solid in water or some other solvent, from which the solid has precipitated.

On the other, other hand, a #"colloid"# is an inhomogeneous mixture of solid and solvent, a disperse phase, in which the particle size of the solid is such that it does not tend to settle. Typical colloids, say milk, have particle sizes from #1*nm-1*mum#.........

Colloids have particles intermediate in size between solutions and suspensions. Suspensions have larger particles that settle over time. True solutions have uniformly dispersed particles at the molecular or ionic level.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
