Is a suspension a homogeneous or a heterogeneous mixture? What about a colloid?

Answer 1

A suspension is definitely a mixture of two phases.........

A suspension is definitely a mixture of two phases.........and thus a suspension is definitely #"heterogeneous"#. A #"colloid"# does not fall under this umbrella, inasmuch as particle size in your typical colloid, is approx. #(1-5)xx10^-9*m#, whereas particle size in a suspension is approx. #1000xx10^-9*m#.

As a practical result, suspensions settle out gradually on standing while collisions do not.

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.
