Mauveine, also known as aniline purple and Perkin's mauve, was the first synthetic organic chemical dye, [69] [70] discovered serendipitously in 1856. Its chemical name is 3-amino-2,±9-dimethyl-5-phenyl-7-(p-tolylamino)phenazinium acetate.
List of largest stars. Appearance. Not to be confused with List of most massive stars. Below are lists of the largest stars currently known, ordered by radius and separated into categories by galaxy. The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,300 mi). [ 1 ] The Sun, the orbit of Earth, Jupiter, and ...
The term blue generally describes colours perceived by humans observing light with a dominant wavelength that's between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet.
It is a purplish-black crystalline salt, that dissolves in water as K + and MnO−. 4, an intensely pink to purple solution. Potassium permanganate is widely used in the chemical industry and laboratories as a strong oxidizing agent, and also as a medication for dermatitis, for cleaning wounds, and general disinfection.
Galileo [9] [10] discovered the Galilean moons. These satellites were the first celestial objects that were confirmed to orbit an object other than the Sun or Earth. Galileo saw Io and Europa as a single point of light on 7 January 1610; they were seen as separate bodies the following night. [11] Callisto: Jupiter IV o: 8 January 1610 p: 13 ...
Manganese in oxidation state +7 is represented by salts of the intensely purple permanganate anion MnO − 4. Potassium permanganate is a commonly used laboratory reagent because of its oxidizing properties; it is used as a topical medicine (for example, in the treatment of fish diseases). Solutions of potassium permanganate were among the ...
Iodine crystals sublimating into a purple gas. In 1811, iodine was discovered by French chemist Bernard Courtois, [10] [11] who was born to a family of manufacturers of saltpetre (an essential component of gunpowder). At the time of the Napoleonic Wars, saltpetre was in great demand in France.
Salmon, chicken, tuna, Greek yogurt, egg whites, and purple sweet potato are some of my favorites to fill my plate. All that said, I never deprive or restrict myself. If I want dessert, I have it.
