Question

Are tea and coffee solutions homogeneous mixture why you say so

Answer 1

Explanation:

_______________________________________

•Answer:-

Yes tea and coffee solutions are homogeneous mixtures.

•Reason with Example:-

Homogeneous and heterogeneous depends on the scale of the observation.

If we observe any mixture sufficiently in detail, it is always heterogeneous (because a mixture is not a solution, the substances in a mixture remain always separate; in a solution, there is a chemical bound between the components).

For example, mayonnaise is a mixture; a good mayonnaise is homogeneous (the oil, eggs and air are well mixed together), a bad one may have oil separated from the rest, but looked at the microscope they are separate, hence microscopically it is heterogeneous.

And at the atomic and molecular level, even a solution is heterogeneous: if you dissolve some salt in water, the salt molecules are split in iones Na+ and Cl-, that interact with water that is split in OH- and H+, giving NaOH and HCl. Hence you have three types of molecutes, NaOH, HCl and H2O. And at the atom level you have four types of atoms. (Na, Cl. O, H).

So the issue is not clear cut. Tea is partly a solution, (caffeine is soluble in water) but parly it isn’t: some leaf fragments always remain in subspension.
