Question
If there is too much sample in the Capillary tube we will observe a sharp endpoint. The melting point of a substance is the temperature at which a substance changes from the solid to the gaseous state. Insoluble impurities will affect the melting point range of an unknown compound. The melting point of an organic compound is a chemical property. Wet samples will have no effect or the melting point determination. You are given 5 compounds with known melting point ranges and you are also given 1 unknown compound. If the instructor has given you an unknown sample, how can you determine its identity using the 5 known compounds? Please explain.
Explanation / Answer
17. Flase
18. Flase
The temperature at which solid substance changes to liquid is called melting point
19. Flase
insolunle salt not effect the melting point
20 Flase
melting point is physical property
