WitrynaMelting point (m.p.) analysis can also provide information about the purity of a sample. A substance (solid) containing soluble impurities usually melts at a lower temperature than the pure compound. It can also melt over a wide range of temperatures and is called the “melting point depression.”

WitrynaImpurity defect Symmetrical patterns in crystal arrangement may be called defects or imperfections of solid. Defects happen faster because particles are closely packed in a solid and they do not rearrange themselves. Small crystals are arranged together closely and made solid. WitrynaIn an ideal situation the solubility product of the impurity, B, is not exceeded at any temperature. In that case, the solid crystals will consist of pure A and all the impurities will remain in the solution. The solid crystals are …
