金属与酸反应的常用规律(The common law of the reaction between metal and acid) The common law of the reaction between metal and acid 1. the reaction of metals with acids is a redox reaction, and the amount of metal that loses electrons is equal to the amount of material that acids yield...
Metallic titanium is dissolved in an aqueous solution of telluric acid, the liquor evaporated, preferably at temperatures below 78 DEG C., to produce a sludge, the sludge dried to form a powder, and the latter heated to 800--1700 DEG C., the resultant product being cooled out of contact...
1, active metal and acid reaction (metal to metal metal hydrogen in the sequence of activities before, not including acid concentrated sulfuric acid and nitric acid) such as Fe2HCl=FeCl2+H2 hav'e Mg+ 2HCl = MgCl2+ H2 = H2SO4 + Fe = H2 = FeSO4+ 2HClZn = ZnCl2 + H2 = H2SO4 + ...
of dissolving a metal in strong acids, one can use the electrochemical series of metals. Metals, which are on the left side from hydrogen in electrochemical series, react with strong acids and release hydrogen. Sulfuric acid and nitric acid, depending on their concentration in the solution, ...
A barrier coating comprising the reaction product of a polymeric material and an acid is disclosed. Methods for improving the barrier of a substrate, and substrates treated according to this method are also disclosed.

Additional measurements performed at 740 Torr were carried out in a quartz-lined metal reactor sampled through the end wall. The higher-pressure experiments produced CH3and OD by reaction of F atoms (formed by 248 nm photolysis of XeF2) with CH4and D2O in the presence of ~1018 cm−...
A composition is disclosed that comprises the reaction product of an acidic organic compound, a boron compound, and a basic organic compound. The composition is useful as a detergent additive for lubricants and hydrocarbon fuels.
Chelating diamido ligands of formula [C6H4{N(SiMe2X)}2-1,2]2, abbreviated as L′2 (X=CHCH2) or L2 (X=Me), were used to prepare di(amido)metal(IV) chlorides [{M(Cl)L′(μ-Cl)(thf)}2] (M=Zr 2 or Ti 3), ZrCl2(L′) 5 and [ZrCl2(L)(tmen)] 6 a... StephaneDani...
