teting Point Measurement and Correction
Approximate melting point of unknown compound:
85 – 96 °C
Select an appropriate melting point standard with a melting point closest to the approximate melting point of your unknown
compound.
Choose the standard:
A. 98 – 100 °c
Choose...
B. 160 – 162 °C
C. 252 - 254 °C
Measured absolute melting point of the standard:
96 - 98 °C
Measured absolute melting point of the unknown compound:
90 – 94 °C
Compare the reported and experimental melting points of the standard to determine if any corrections need be done for your unknown
melting point.
Correction (°C):
Corrected melting.point of unknown compound
