Dichlorophenol pka
2,6-Dichlorophenolindophenol (DCPIP, DCIP or DPIP) is a chemical compound used as a redox dye. When oxidized, DCPIP is blue with a maximal absorption at 600 nm; when reduced, DCPIP is colorless. DCPIP can be used to measure the rate of photosynthesis. It is part of the Hill reagents family. When exposed to light in a photosynthetic system, the dye is … WebThe phenol derivative picric acid (2,4,6 -trinitrophenol) has a pK a of 0.25, lower than that of trifluoroacetic acid.
