The Effect Of DCPIP On The Rate Of Photosynthesis

Witryna4 mar 2024 · DCPIP can exist as a solution in two forms, depending on the pH of the medium: protonated (DH, “pink” form) and deprotonated (D –, “blue” form) with an absorption maxima at 515 and 605 nm, respectively.When these forms are reduced, H 2 D – and H 2 DH products are formed, which practically do not absorb light in the … WitrynaSodium sulfate and methylene blue were purchased from BDH Chemicals Ltd.
