WebpK a of Methyl Red 1-3 Purpose: The pK a' of methyl red will be determined by measuring absorbance spectra as a function of pH. Introduction Methyl red (4-dimethylaminobenzene-2’-carboxylic acid) is a commonly used indicator for acid-base titrations. We will measure the visible absorption spectra of the acidic and basic forms of this compound. Web1 jan. 2015 · The UV–vis spectrum during the dye degradation was measured at 200–800 nm using a UV–vis spectrometer (UV765, Shanghai Precision & Scientific Instrument Co., Ltd., China). The intermediates formed during the degradation of methyl orange were analyzed using FT-IR (Nicolet 5700, Thermo Electron Scientific Instruments Co., Ltd., … texas tower pune
