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 ...
2,6-Dichlorophenol is a compound with formula C 6 H 3 Cl 2 OH. It is one of the six isomers of dichlorophenol. It is a colorless solid. Its pK a is 6.78, which is about 100x more acidic than 2-chlorophenol (8.52) and 1000x more acidic than phenol itself (9.95). [3]
Unlike the photo-oxidative bleaching of methylene blue, [22] they use the underlying semiconductor photocatalyst film to photoreduce the dye (D ox in figure 2), in the ink coating, to another (usually colourless) form, (D red in figure 2) whilst simultaneously oxidising an easily oxidised organic species, a sacrificial electron donor (SED ...
Signal word: "Danger" or "Warning" will be used to emphasize hazards and indicate the relative level of severity of the hazard, assigned to a GHS hazard class and category. Some lower level hazard categories do not use signal words. Only one signal word corresponding to the class of the most severe hazard should be used on a label.

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
While many cases go unreported, "the U.S. Centers for Disease Control and Prevention (CDC) estimates that 48 million people – about 1 in 6 Americans – get sick from foodborne illnesses each ...
