WebMelting point is also when a substance’s intermolecular forces are broken. There is a lot of information that can be obtained from the measurement of melting points. Melting points can allow one to know if an unknown substance is pure or impure. Observing melting point can also show how strong a substance’s intermolecular forces are. Web28 aug. 2024 · August 28, 2024 by Alexander Johnson. Impurities, even when present in small amounts, usually lower the melting point and broaden the melting point range. A wide melting point range (more than 5°C) usually indicates that the substance is impure; a narrow melting point range (O. 5-2°C) usually indicates that the substance is fairly pure.
