How much of acid concentration (H+) is needed to protonate the amine group (-NH2) of the chitosan biopolymer?
Amino groups in chitosan biopolymer are completely protonated in acid with pKa value from 6.0 to 6.5.
@Nirmla! Thank you, for your contribution.
Hello What should be done to separate and identify organic acids in HPC when their RetTime is the same?Like oxalic acid with Propanoic Acid.or acids that have a very close RetTime.

why don't d-orbitals split themselves because of themselves without the presence of ligands? Electrons are indistinguishable. Why wouldn't it be more correct that protons from a ligand split the...

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...
