Explanation:

The observation that can make the chemist conclude that the liquid is a pure substance is if the unknown liquid composition is the same at every point of sampling.

  • Pure substances are distinct substances.
  • They have a definite composition.
  • All the parts are the same throughout.
  • They cannot easily be separated or broken down into simpler substances by physical means.
  • They have a unique set of physical properties.

Therefore, if his analysis meets any of the criteria for defining a pure substance above, he can conclude that it is one.

Pure substances are elements and compounds.
