MELTING POINT DETERMINATION Name: Grade Course: Tutor`s Name: (7, July 7, 2011) Melting Point Determination Title: melting point determination Purpose: to determine melting of an unknown substance and ensuring that it is identified Experimental: Determining melting point range for re-crystallized acetalide, a 50/50 mixture of pure acetalide, benzoic acid and melting point of unknown substances. Experimental set-up
Taking small amount of sample, putting it in the capillary tube, and mounting it on thermometer. Take the temperature at the initial start of melting of the substance. Heat the substance and take the temperature at the final melting of the substance. Repeat this process more than once to come up with a consistence results.
