The melting point of pure aspirin is typically around 135-136°C, while the melting point of aspirin prepared in a lab could vary depending on the purity of the synthesis process. Impurities in lab-prepared aspirin can lower the melting point or broaden the melting range compared to pure aspirin.

One way to determine the purity of aspirin is through a melting point test. A pure sample of aspirin will have a specific melting point range, so comparing the observed melting point to the known range can indicate purity. Additionally, techniques such as chromatography or spectroscopy can be used to analyze the composition of the sample.
No, sugar does not affect the melting point. The melting point of a substance is determined by its chemical composition and structure. However, adding sugar to a solution can affect its boiling point, but that is a different property.
melting point- 136 degree C boiling point- 140 degree C
No, the color of a candle does not affect its melting point. The melting point of a candle is determined by the type and quality of wax used, not by its color.
The melting point of crude and recrystallized aspirin is used to assess the purity and quality of the sample. A sharp and consistent melting point indicates a pure compound, while a broader range or lower melting point may indicate impurities or incomplete purification. This information is important for quality control in drug manufacturing.

Minerals with higher melting points will increase the overall melting point of a rock. Conversely, minerals with lower melting points will decrease the overall melting point. The composition and proportion of minerals in a rock will determine its melting point.
Water reduces the melting point of rock.
Adding salt to water the freezing point decrease.
