NettetHence, different compounds tend to have different melting points. A pure, nonionic, crystalline organic compound usually has a sharp and characteristic melting point (usually 0.5-1.0 C range). A mixture of very small amounts of miscible impurities will produce a depression of the melting point and an increase in the melting point range. Nettet2. mai 2024 · All generalities are false (as is this one). Though impurities usually lower the melting point (m.p.) by disrupting crystallization on the atomic order, consider the phase diagram of the binary alloy (amalgam) Hg x Ag 1- x: Pure Hg melts ~-39°C, and adding even a little bit of impurity raises the melting point considerably!.
