Purple liquid with atomic number 11 and symbol Re that makes a compound that produces clouds when exposed to air when mixed with Arsonium, and an antivirus when mixed with Nanite and Sanite. The real element 11 is sodium; and Re = rhenium. Residuum Critical Role, The Legend of Vox Machina: A mineral; can enhance arcane powers. Refined from ...
Aerinite (Ca 4 (Al,Fe,Mg) 10 Si 12 O 35 (OH) 12 CO 3 ·12H 2 O) is a bluish-purple inosilicate mineral. It crystallizes in the monoclinic system and occurs as fibrous or compact masses and coatings. It has a dark, vitreous luster, a specific gravity of 2.48 and a Mohs hardness of 3.
Tyrian purple is a pigment made from the mucus of several species of murex snail. Production of Tyrian purple for use as a fabric dye began as early as 1200 BC by the Phoenicians, and was continued by the Greeks and Romans until 1453 AD, with the fall of Constantinople.
Carmine dyes, which give crimson and related red and purple colors, are based on an aluminium and calcium salt of carminic acid. Carmine lake is an aluminium or aluminium-tin lake of cochineal extract, and crimson lake is prepared by striking down an infusion of cochineal with a 5 percent solution of alum and cream of tartar.
A permanganate (/ p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) [1] is a chemical compound with the manganate(VII) ion, MnO − 4, the conjugate base of permanganic acid.Because the manganese atom has a +7 oxidation state, the permanganate(VII) ion is a strong oxidising agent.
Murexide (NH 4 C 8 H 4 N 5 O 6, or C 8 H 5 N 5 O 6 ·NH 3), also called ammonium purpurate or MX, is the ammonium salt of purpuric acid.It is a purple solid that is soluble in water. The compound was once used as an indicator reagent. [1]
The purplish-black color of solid potassium permanganate, and the intensely pink to purple color of its solutions, is caused by its permanganate anion, which gets its color from a strong charge-transfer absorption band caused by excitation of electrons from oxo ligand orbitals to empty orbitals of the manganese(VII) center.
The required liquid complexone is made by dissolving 10 mg o-cresolphthalein complexone in 50 mL alkaline borate [clarification needed], and then 50 mL of 0.05 N HCl are added to make the solution's pH 8.5. This method for calcium determination is efficient and effective, requiring a minimal amount of blood serum sample and a reasonable amount ...
