This article summarizes the protonation and complexation equilibrium constants of nicotinic acid (NA) using different analytical techniques and software’s. Additionally, Raman, IR, and NMR spectra were done for nicotinic acid ligand and for its solid complexes with copper(II), cobalt(II) and nickel(II) metal ions.


KEY WORDS: Nicotinic acid, Potentiometry, Spectrometry, Equilibrium constants
