Melting Point Lab Report Essay Example

Melting Point Lab Report Paper 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. I did a mixed melting point trial to find out what substance I had. I used Benzene Acid and Ecumenicist because they were the two substances in my melting point range. Just by comparing the characteristics of the two substances to my unknown, I assumed it to be Benzene Acid. My unknown and Benzene Acid had a fine, powdery texture to it, while Ecumenicist looked like crystals. The two mixed melting point range trials infirmed this. Unknown number 18 is Benzene Acid. A possible alternative would be Ecumenicist, because of the close melting points. Another possible alternative is Fluorine, which melts at slightly lower temperatures than my unknown does. Benzene Acid is CHICHI. Its structure is: My percent recovery was 28. 26%. During the dissolving of my unknown, there was still undisclosed solid. This could have led to a smaller percent recovery. If you are not given the solubility data for your compound, then you must test for the solvent required. This is done by mixing the possible solvent and your solid gather and agitating it, heating it, then cooling it.

You dissolve your solid by using a hot solvent, and then cool it down to form crystals. The solution is heated so the solid can dissolve and the filtrate is cooled to lower the solubility, which causes the crystals to form.
