Unknown 33a Lab Report

Satisfactory Essays

In order to discover the melting point range of Unknown 33A, a Digimelt was utilized. Melting point is the temperature at which a crystalline structure changes from solid to liquid. By adding thermal energy, the structure changed from solid to liquid. The thermal energy increased the kinetic energy, which then overcame the intermolecular attractive forces between the molecules. This increase in speed allowed the molecules to move more freely. By identifying the melting point range of Unknown 33A, it narrowed the possibilities of the unknown by ruling out the compounds with melting points greater than ± 20°C from Unknown 33A’s melting point range.

The average melting point range of Unknown 33A was 52.1°C-54.2°C (32.1°C-74.2°C), which represents
