  2. Prussian blue - Wikipedia

    en.wikipedia.org/wiki/Antwerp_blue

    It has the chemical formula Fe 3+ 4 [Fe 2+ 6] 3. Turnbull's blue is essentially identical chemically, excepting that it has different impurities and particle sizes—because it is made from different reagents—and thus it has a slightly different color. Prussian blue was created in the early 18th century and is the first modern synthetic pigment.

    A sample of one kind of molybdenum blue with the formula Na 15 [Mo VI 126 Mo V 28 O 462 H 14 (H 2 O) 70] 1 ⁄ 2 [Mo VI 124 Mo V 28 O 457 H 14 (H 2 O) 68] 1 ⁄ 2. [1] Molybdenum blue is a term applied to: reduced heteropolymolybdate complexes, polyoxometalates containing Mo(V), Mo(VI), and a hetero atom such as phosphorus or silicon

  4. Methylene blue - Wikipedia

    [48] [46] The redox properties can be seen in a classical demonstration of chemical kinetics in general chemistry, the "blue bottle" experiment. Typically, a solution is made of glucose (dextrose), methylene blue, and sodium hydroxide. Upon shaking the bottle, oxygen oxidizes methylene blue, and the solution turns blue. The dextrose will ...

    YInMn Blue (/jɪnmɪn/; for the chemical symbols Y for yttrium, In for indium, and Mn for manganese), also known as Oregon Blue or Mas Blue, is an inorganic blue pigment that was discovered by Mas Subramanian and his (then) graduate student, Andrew Smith, at Oregon State University in 2009.

  8. Brilliant blue FCF - Wikipedia

    The chemical formula is C 37 H 34 N 2 Na 2 O 9 S 3. Related dyes are C.I. acid green 3 (CAS#4680-78-8) and acid green 9 (CAS#4857-81-2). In these dyes, the 2-sulfonic acid group is replaced by H and Cl, respectively. [8] Many attempts have been made to find similarly colored natural dyes that are as stable as brilliant blue FCF.
