I have my final report and I have 2 questions about it. So our final product was a brown crystalline solid that had an absorbance at about 880nm. My first question is how is brown reflected (not in a literal sense) in the visible spectrum? that's outside visible region and I could find nothing about brown solids and absorbance in my book or online? My last question is why were having a steady stream of oxygen to the first part? was it to act as an oxidizing agent to cobalt?© BrainMass Inc. brainmass.com March 22, 2019, 1:25 am ad1c9bdddf
Brown is a very interesting color. It is formed from a combination of other colors and hence can go somewhat past the traditional ...
The reason for the use of O2 in the preparation of cobalamin complex is given. A discussion of identifying brown solids in the absorbance spectra is also included.
