I.         Objective(s): To determine the melt down points of 2 unknown compounds. II.         Procedure: 1) adjust a small quantity of unknown A in a capillary tube. 2) Setup                                 3) Place into the hot water.                                 4) make up till chemical substance melts.                                 5) Lift clamp off of water.                                 6) magnetic disc the temperature at which it crystallizes.                                 7) Repeat for 3 well behaved values.                                 8) Repeat 1-7 for chemical B. III. Results:                                 A                         B Melting Points (C):         1) 70.1                 1) 60.8                                 2) 70.3                 2) 70.8                                 3) 72.6                 3) 71.4 mean(a):                         71                         67.7 VI. hallucination Analysis: 1) One problem we had was estimating the temperature of the melting point because we werent quick enough to read it onwards it started to cool smooth. 2) We had difficulties toilsome to tie the little tube to the .7                                 72.6 - ! 71                 1.6 Chemical B                 x         x                 x-x                                 60.8 -         67.7                 6.9                                 70.8 -         67.
