Melting range 793-801 degrees c are recovered what conclusions can you draw from the melting ranges this question is from my inorganic chemistry i do not really understand the importance of the melting ranges. I did three mixed melting point trials that resulted in a melting point of 1 icc to 1 icc the melting point range is small, which indicates a relatively pure substance. Determining the melting point of a compound is one way to test if the substance is pure a pure substance generally has a melting range (the difference between the temperature where the sample starts to melt and the temperature where melting is complete) of one or two degrees.

Melting point range for 1-tetradecanol: 37-40 degrees celsius melting point range for mixture: 34-37 degrees celsius i was instructed to record a melting point range for each compound, rather than a single melting temperature of different polymerstemperature melting point.
Melting point of a compound is the temperature at which it changes from a solid to a liquid experimentally, melting point is actually recorded as the range of temperatures in. Melting point range of 132 - 133oc but if it is significantly contaminated, it will have a but if it is significantly contaminated, it will have a lower melting point with a broader range (say, 125 – 130 o c, for example).

A melting point is the temperature at which a material melts at atmospheric pressure1 melting points are usually expressed as a range between when the material begins to melt and when it has completely melted. The purpose of melting and boiling points in a lab experiment is to use them to help identifiy unknown substances by taking a melting point of an unknown solid, you can compare it to a list of . Laboratory exercise: melting and boiling points the melting range 6 heat your sample until melting is observed typically, samples will melt over a 1-2oc.
The melting point range of greater than 5 °c indicates that the substance is impure for a material whose identity is known, an estimate of degree of purity can be made by comparing its melting .
