Consider the following scenario: a small amount of a solid got into a sample when preparing the capillary tube to determine its melting point. The student decided to take the melting point anyway. The student observes the following: (a) a sharp melting point (<2oC); (b) a melting point that closely matches the literature reported value. Which of the following conclusions will not be justified by the experimental results.

Question
Consider the following scenario: a small amount of a solid got into a sample when preparing the capillary tube to determine its melting point. The student decided to take the melting point anyway. The student observes the following: (a) a sharp melting point (<2oC); (b) a melting point that closely matches the literature reported value. Which of the following conclusions will not be justified by the experimental results.
- The solid was a soluble impurity in the liquid phase.
- The solid was an insoluble impurity in the liquid phase.
- The solid was a sample of the same compound.
