This is a commercially important reaction for preparing hydrogen chloride and hydrogen bromide. The acid-base reaction between a nonvolatile strong acid and a metal halide will yield a hydrogen halide. The escape of the gaseous hydrogen halide drives the reaction to completion. For...

Hydroiodic acid Acute and short term toxicity (animal/human) Animal One rat skin study compared the relative toxicity of hydrogen iodide, hydrogen bromide, and hydrogen chloride (Quevauviller et al., 1974). Hydrogen bromide caused the most severe burns followed by hydrogen iodide in the rats. ...
To make the hydrogel microfiber visible in the dark, we functionalized the microfiber by doping a fluorescent agent, 8-anilinonaphthalene-1-sulfonic acid (ANS), into the spinning dope, which is known to exhibit strong fluorescence in the hydrophobic environment52. Owing to the presence of ...
For instance, β-ketoenamine linked COF exhibited strong resistance toward acid (9 M HCl), base (9 M NaOH), and boiling water37,38. Thus, they have shown great potential in various applications such as cata- lysis, energy storage, water splitting, and molecular separation39–43. In this ...
have designed an experiment to demonstrate the ability of hydrogen storage of BNMSs, which is prepared through the reaction of dicyanamide (Dcy) with boric acid (BA) [102]. Fig. 9a shows a diagram of a facile one-step synthesis approach of the BN microsponges, and HRTEM image of BN ...
H2O or H2O2. Catalyst materials with strong oxygen binding energies could be excluded due to favorable *O formation [37,38]. Accordingly, 2e–-ORR involves only one intermediate *OOH, no matter in acid or alkaline media. The adsorption-free energy of *OOH (ΔG*OOH) is used to quantify ...
The title compound comprises a protonated creatininium cation and a deprotonated hydrobromic acid anion. Table 2 summarizes the selected geometrical parameters of the compound. The crystal packing of the compound was controlled by weak intermolecular NH…Br and CH…Br interactions. Table 3 shows the...
The synthesis of catalysts was carried out by alcohol reduction method using KBr as a shape directing agent (Bromide Anion Exchange method - BAE). The X-ray diffraction (XRD) showed characteristic peaks of the Pt face-centered cubic (FCC) structure, as well as cassiterite SnO2. The ...
The ultrathin RhMo NSs were prepared by a facile one-pot wet-chemical method, in which dodecarbonyltetrarhodium (Rh4(CO)12) and molybdenum carbonyl (Mo(CO)6) were used as metal precursors, potassium bromide (KBr) and citric acid monohydrate (C7H8O.H2O, CA) as the structure-directing...
