Is Ca(OH)2 an acid or base? How are Ka and Kb values of an acid and base used to determine the acidic or basic nature of their aqueous salt solution? Applying this process, determine if a salt solution of NH4ClO2 is acidic, basic, or neutral. ...
ammonium niobium oxalate NH4[NbO(C2O4)2(H2O)2].(H2O) dissolved in water, adding oxalic acid, to precipitate niobic acid, extruding to form a shaped body, which is sprayed with ammonium sulfate as promoter, drying and calcining, adding hexachloroplatanic ac ...
Briefly, 200 μL of 0.5 mM 15NH4+ solution was added to each bottle, which was then terminated at 4 h and 8 h, respectively. To measure the concentration of 15NO2−, 100 μL of 16.5 mM sulfamic acid (H3NO3S) was added aiming to reduce 15NO2− to 29N2. The...
aThe rate of loss then slows as NH4+-N concentration decreases, pH reduces, NH4+ incorporates into the soil, and a surface crust is formed after manure is applied. 损失的率然后减慢,当NH4+-N集中减少,酸碱度减少, NH4+合并到土壤里,并且一个表面外壳被形成,在肥料是应用的之后。[translate]...
