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
[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 ...
Bromothymol blue (also known as bromothymol sulfone phthalein and BTB) is a pH indicator.It is mostly used in applications that require measuring substances that would have a relatively neutral pH (near 7).
Chemical structure of copper phthalocyanine. Copper phthalocyanine ("phthalo blue") is a synthetic blue pigment frequently used in paints, inks, and dyes. It is highly valued for its superior properties such as light fastness, tinting strength, covering power and resistance to the effects of alkalis and acids. It has the appearance of a blue ...
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.
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.
Tris(4-bromophenyl)ammoniumyl hexachloroantimonate is the organic compound with the formula [(4-BrC 6 H 4) 3 N]SbCl 6. [1] Commonly known as magic blue, it is the hexachloroantimonate salt of an amine radical cation. It is a blue solid that reacts with many solvents but is soluble in acetonitrile.
