dear colleagues,
I want to set the methylene blue dye condition under the addition of NaOH and HCl so the acid, neutral and base condition have resulted. However, sometimes, it has distrubed me to konw deeply what's their mechanisms in micro system or dye compound-ions counterpart under the acid, neutral and base condition. Any literature to describe about this?
Dear F. Febiyanto
Please can you explain what is the target of the question?
Regards
It should be attributed to the state of the electrons in the conjugate system, which affect the absorption of photons with different frequencies
Your question is not well formulated. I don't understand what is " it has distrubed me to konw deeply what's their mechanisms in micro system or dye compound-ions counterpart under the acid, neutral and base condition "
Methylene blue has pKa about 4, it can form aggregates (dimer, trimer, etc), it has the redox potential around -0.1 V. The spectra of different forms are different.
