Is a colloid a heterogenous mixture?

Answer 1

A colloid is actually a heterogeneous mixture.

HETEROGENEOUS MIXTURE- Heterogeneous mixture means the mixture in which the particles are not uniformly mixed with each other.

In a colloid the particles are very very minute and so are not visible to our eyes. For example milk is colloid.

So according to me colloid mixture appears to be a homogeneous mixture but actually it is a heterogeneous mixture.

Answer 3

No, paint is a Colloid.

Answer 2

I disagree....... A colloid is heterogenous, since it has a disperse phase (eg. solid particles) that is distributed across a disperse medium (eg. a solvent) - and yes many paints are colloids but this is irrelevant. Although a colloid may be considered heterogenous, it should (and must) not be confused with that of a suspension (another class of heterogenous mixtures). The disperse phase of a suspension will settle out to form a sediment over time, whereas the disperse phase of colloids do not (thus their formation is irreversible).

The particles in a colloidal system remain in a 'dispersed state' because they are of a size that is too small to be infulenced by the gravitational field and thus do not settle out of the disperse medium over time.

This is what fundementally distingushes a colloidal system from a suspension. But they are both heterogenous mixtures never the less!

It is helpful to remember that from a scalar point of view, the disperse phase of colloids is classified between the very small scale of solution particles (individual ions) and the relatively large scale of suspension particles (visible 'macromolecular clusters').

Hope this helps

Good luck.

Answer 4

By convention or definition, a colloid is considered a heterogeneous mixture, because the particles of the disperse phase of the colloid are large enough to scatter visible light and are therefore considered a different phase from the continuous phase.

Answer 5

Yes, the majority of colloids are heterogeneous. However, there are a few types that are considered homogenous like raw eggs.

Answer 6

Yes, a colloid is a mixture.

The definition of a colloid is a type of mixture with particles that are larger than those in solutions but not as heavy enough to settle out.

Answer 7

yes a collloid is a homogeneous

Answer 8

Is a hetrogenous mixture.
