It can be sublimed in vacuo, and readily at room temperature. It has also been purified by removal of water during azeotropic distillation of a *benzene solution. It is then recrystallised twice from anhydrous diethyl ether under argon, and stored under argon [Blackstock et al. J Org Chem ...
Stannous Sulfate is a white to slightly yellow, heavy crystalline powder. When dissolved in a 5% Sulfuric Acid Solution, a clear solution is obtained. Gradual hydrolysis occurs over a period of time with the formation of insoluble tin compounds....
complexes with donor ligands. It possesses low solubility in water but dissolves in polar organic solvents like ethanol and dioxane. While stable in solution, it can hydrolyze into boric acid when exposed to moisture or basic substances. Proper storage in a dry, well-sealed container is essential...
What I do not (yet fully) understand is the role of the chloride in the electrolysis experiment. When you perform electrolysis of a solution of NaOH, then you get O2 at a copper anode! When, however, quite some NaCl is mixed in, then you get the yellow copper (I) compound. Apparently...
Research shows that Ligustilide has strong antispasmodic, antiasthmatic, and sedative effects, can improve microcirculation, relax smooth muscles, inhibit bacteria, and improve the body's immune regulatory function. It is a typical representative of phthalide compounds. It is mostly found in Umbelliferae...
Every scientific discipline has its characteristic set of problems and systematic methods for obtaining their solution-that is,its paradigm.Chemical engineering is no exception.Since its birth in the last century,its fundamental model has undergone a series of dramatic changes.TRADITIONAL PARADIGMS OF ...
About HClO + Cl- + H+ -> Cl2 + H2O I think there is too much Cl2 production that needs a lot of Cl- ions in solution.Maybe too much for being due to dissociation on NaClO, but I´m not sure. About the ClO2, i´m not sure if i can write the reaction...What would be ...
In this article I’ll talk about why that is dangerous, especially if you have autoimmunity, chemical sensitivities, or symptoms of compromised brain function. Chelation often makes people much worse, and it is not due to a “detox reaction” as many practitioners will tell you. Why toxins ...
Bis-(sodium sulfopropyl)-disulfide is a white to light yellow solid powder, mainly used in acid copper plating brightener, and can obtain decorative and functional coatings (such as printed circuit boards). Bis-(sodium sulfopropyl)-disulfide can be used with typical copper-plated formulations such...
The climate of both target regions reveals a humid regime with a comparable annual course of precipitation totals and mean temperature. However, the Lusatian region is among the driest regions in Germany [17] with a negative climatic water balance due to a more continental character, while the ...
