Is coffee a mixture or pure substance?
Coffee is a mixture. Pure substances are elements (e.g., 100% gold, silver, oxygen, etc.) and compounds like sodium chloride, sugar, etc. Distilled water is a pure substance (H2O); however tap water is a homogeneous mixture as it contains other minerals in it.

When is coffee a mixture, compound, or solution?
Coffee can be both a mixture and solution: It is a mixture at any point, but more specifically, when the makeup is uneven, and the coffee is ground. It is a solution only when it is properly dissolved in the water and has the same balance. Coffee is never a compound because it is made using a physical change, not a chemical one.

What is the difference between a solution and a mixture?
Coffee is a solution, not a compound or mixture, as it includes a solute that dissolves into a solvent. Compounds must be bonded chemically, and mixtures have visibly separate parts. Coffee can also be considered a mixture since it involves two mixed substances, but this is too vague.
