Procedure 3.3 Thermal Analysis of Green and Brown

Weigh out 4-5 mg sample (this may be modified depending on instrumentation). 

For your green complex, complete two consecutive runs. Note any physical changes in your sample. 

Complete the Post-lab Questions and Results Summary Worksheet. 

Analysis of observed thermal transition—fill in the table of enthalpy changes in Table 3.6 for the observed thermal transition (see help below). Use the following questions to help fill in the table.
