Chemistry Lab : Determining the melting point

I.         Objective(s): To determine the melt down points of 2 unknown compounds. II.         Procedure: 1) lay a small mensuration of unknown A in a capillary tube. 2) setup                                    3) Place into the hot water.                                    4) buy the farm till chemical nerve centre melts.                                    5) Lift clamp let out of water.                                    6) magnetic disc the temperature at which it crystallizes.                                    7) Repeat for 3 vertical 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 add up:                           71                           67.7 VI. hallucination analysis: 1) One problem we had was estimating the temperature of the melting point because we werent flying enough to read it earlier it started to cool smooth. 2) We had difficul nexuss trying to tie the little tube to the .7                                    72.6 - 71                  1.6 chemic B                  x          x                  x-x                                    60.8 -          67.7                  6.9                                    70.8 -          67.

It took a lot of measure and patience to do that. 3) Chemical A                  X          X                  X-X                                    70.1 -          71                  .9                                             70.3 -          71                   If you fatality to get a exuberant essay, order it on our website: Orderessay
