You are given a liquid. briefly describe the steps you would take to show whether it is a pure substance or a homogeneous mixture.

By using any one technique like boiling, distillation, condensation ,etc , one can be used to distinguish between a pure substance and a homogeneous mixture.

Explanation:

If the liquid is a pure substance, then it can not be separated by using physical means because all atoms of a pure substance show same properties.

But on the other hand, if there is homogeneous mixture, it can be separated by using techniques like boiling, distillation, condensation ,etc.

Thus, using any of the one method listed above can be used to distinguish between a pure substance and a homogeneous mixture.
