C. Analysis and Discussion
1. Standardization of NaOH
The main purpose is to determine the exact concentration of NaOH before
proceeding with experiment 3 as the concentration might have changed due
to external factors such as temperature.
EXPERIMENT 2 : Chemical Kinetics
: Caroline Evania Mulijanto
Lab Group : Tu 2
Matric No : A0073242
To determine the reaction orders m and n with respect to S2O82- and I- respectively
To identify and isolate the organic molecules, namely Chlorophyll and -Carotene found in plants by
means of column chromatography and UV-Vis spectroscopy.
In order to separate the chlorophyll and -carotene present in a plant sample, column ch
1. Examine the total electronic energy of N2 and compare it to the total electronic
energy of H2.
Total electronic energy of N2 = -107.49419434 a.u
Total electronic energy of H2 = -1.11615145 a.u
Why are the numbers negative?
Total electronic energy is
