Melting Point Determination Lab Materials: Graduated pipette Capillary tube Tin wipe Sample Melting temperature apparatus Thermometer Procedure: Take open end of capillary tube and tap it gently into sample. Take tin wipe and place over the opening. Gently tab it so the sample will funnel to the bottom of the tube. You may also use a graduated pipette to accomplish this. Now‚ place the capillary tube in the designated spot in the melting apparatus‚ and once placed‚ turn the apparatus

Mixture Melting Points Abstraction Determining the melting point is very significant in order to identify an unknown. In this experiment‚ measuring the melting point was done by using melting point apparatus. The melting point of the unknown sample #10 was 111.5˚C. There were two possible compounds which were dibenzoyl ethylene and o-Toluic acid because their melting points were 111.2˚C and 109.8˚C when each compound was mixed with the unknown. Therefore‚ the unknown #10 was dibenzoyl ethylene
