Tin is nontoxic, ductile,malleable, and adapted to all kinds of cold-working, such asrolling,spinning, andextrusion. The colour of pure tin is retained during exposure because a thin, invisible, protective film of stannic oxide is formed spontaneously by reaction with theoxygenof the air. The...
Tin(II) chloride (also known as stannous chloride) is the most important commercial tin halide. Illustrating the routes to such compounds, chlorine reacts with tin metal to give SnCl4 whereas the reaction of hydrochloric acid and tin produces SnCl 2 and hydrogen gas. Alternatively SnCl4 and ...
Stannous monochlortrifluoride (Sn2ClF3) is made by treating a solution of stannous chloride with hydrofluoric acid and crystallizing the solution, in which the solution contains not less than 50 per cent of water by weight and the stannous chloride and hydrofluoric acid are less than 50 per cent...
Tin (IV) chloride appears as white crystals with a strong pungent chlorine odour. On heating, tin (IV) chloride decomposition emits acrid fumes. At room temperature, it is colourless and releases fumes on contact with air, giving a stinging odour. Stannic chloride was used as a chemical wea...

The colour change to red for aged DMSO solution suggests the presence of oxidised Sn species. b List of solvents capable of forming FASnI3 solutions. c PCE distribution of reported devices in literature containing different SnX2 additives. d Normalised PCE evolution at MPP in N2 atmosphere of ...
In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip...
To cure the PDMS, we used an oven at 60 °C for 30 minutes, and in order to detach the PDMS from the silicon mold, we used hot water as an etching solution for the NaCl/Ge sacrificial layer. After 15 mins of etching, the sacrificial layer was fully removed and the ITO-...
Using thymol-sodium hypobromite as chromogenic reagent,and extracting the colour formed with butanol,a spectrophotometric method for the determination of arginine in fermentation broth was studied. 以百里酚的次溴酸钠溶液为显色剂,用正丁醇萃取显色产物,以分光光度计比色测定有机相的吸光度值。 更多例句...
