Question

different between homogeneous and heterogeneous mixture

Answer 1

A homogeneous mixture is a mixture where the components that make up the mixture are uniformly distributed throughout the mixture. The composition of the mixture is the same throughout. There is only one phase of matter observed in a homogeneous mixture. So, you wouldn't observe both a liquid and a gas or a liquid and a solid in a homogeneous mixture.
A heterogeneous mixture is a mixture where the components of the mixture are not uniform or have localized regions with different properties. Different samples from the mixture are not identical to each other. There are always two or more phases in a heterogeneous mixture, where you can identify a region with properties that are distinct from those of another region, even if they are the same state of matter (e.g., liquid, solid).

Answer 2

Homogeneous mixture
1. it has uniform composition.
2.distinct boundary of each constituent is visible
3. for eg. salt in water

Heterogenous mixture
1. it has non uniform composition.
2. distinct boundary of each constituent is notvisible
3. for eg. sand in water
