Answer to Question #99576 in General Chemistry for Nathan Ryan

Question

a pure compound cannot contain what?

Answer 1

A pure compound cannot contain two or more types of atoms or molecules. A pure compound contains only one kind of particle and cannot contain any additional impurities. For example, pure water contains only H₂O molecules and can be considered as a pure compound. If NaCl is dissolved in water, this water sample is not pure compound as it contains traces of Na and Cl.
