Scandium trifluoromethanesulfonate, commonly called scandium triflate, is a chemical compound with formula Sc(SO 3 CF 3) 3, a salt consisting of scandium cations Sc 3+ and triflate SO 3 CF − 3 anions. Scandium triflate is used as a reagent in organic chemistry as a Lewis acid. [1]
Sc 2 (SO 4) 3 Molar mass: 378.09 g mol −1 Appearance white hygroscopic crystals [1] or powder [2] Solubility in water. soluble Hazards GHS labelling: Pictograms.
On 3 December 1982, the Duke of Edinburgh visited Britax's factory in Chichester. The Britax brand also applied to sun-roofs. The Britax brand also applied to sun-roofs. In March 1995, L.A. Rumbold the Surrey-based aircraft interiors company owned by BSG International, won a contract to manufacture all toilet modules for Boeing 737s .
The first step (called SC-1, where SC stands for Standard Clean) is performed with a solution of (ratios may vary) [2] 5 parts of deionized water; 1 part of ammonia water, (29% by weight of NH 3) 1 part of aqueous H 2 O 2 (hydrogen peroxide, 30%) at 75 or 80 °C [1] typically for 10 minutes. This base-peroxide mixture removes organic residues.
Cross sections of a killed tree's main stem are blanched completely white. [1] [2] The white willow, S. alba, is very sensitive to watermark disease, while the crack willow, S. fragilis, is considerably less so. Hybrids of these two species have shown intermediate sensitivity. [2]
Scandium(III) hydroxide is an inorganic compound with the chemical formula Sc(OH) 3, the trivalent hydroxide of scandium. It is an amphoteric compound. [2] It is slightly soluble in water, and its saturated solution (pH = 7.85) contains Sc(OH) 3 and a small amount of Sc(OH) + 2. The solubility of scandium(III) hydroxide in water is 0.0279 mol/L.
