Witrynadifficult to understand how impurities affect the melting point. Foreign substances in a crystalline solid disrupt the repeating pattern of forces that holds the solid together. Therefore, a smaller amount of energy is required to melt the part of the solid surrounding the impurity. This explains the melting WitrynaEffect of Impurities on the Melting Point – Melting Point Depression. Melting point depression is the phenomenon of reduction of the melting point of a contaminated, impure material compared to the pure material. The reason is that contaminations weaken the lattice forces within a solid crystalline sample. In conclusion, less energy …
