sodium hydroxide, ammonium bromide Does a precipitate form when these two are mixed? What is the empirical formula for them? What is the formula for the chlorate ion? A compound has the name thallium(III) nitrate. What is its formula? The symbol of thallium is Tl. ...
tetrabutylammonium bromide in 19 ml of water is stirred at 70° C. for 1 hour. It is allowed to cool and extracted with ethyl acetate. The organic phase is dried over sodium sulfate, filtered and the solvent is evaporated under reduced pressure. The title compound is obtained in the form ...

X- is a pharmaceutically acceptable anion, for example a halide such as iodide, bromide, chloride, sulphate or an anion of an organic acid such as methanesulphonate, benzenesulphonate, nitrobenzenesulphonate and naphthalenesulphonate. Non-pharmaceutically acceptable salts of formula (I) are also includ...
I switched to the bromide over the iodide, and can get rid of most of the bromide via an aqueous wash in saturated NaOAc/Toluene-IPA (down to ~1%), then a few batch process ion exchange resin treatments to get it down to <200ppm Br-.I didnt want to use silver because the final ...
sodium hydroxide, ammonium bromide Does a precipitate form when these two are mixed? What is the empirical formula for them? Write the formulas for the following compounds. a. ammonium hydroxide b. sodium bicarbonate c. calcium acetate d. copper(II) sulfate Write the chemical formula for the ...
Furthermore, aqueous ferrous ions have low solubility and can transform into Fe (OH)3 precipitate at ambient pH ≥ 5. Thus, adjusting the pH of the soil during remediation is necessary to ensure the activation effect [53]. However, this is impractical on a large scale and has ...
