Beryllium sulfate normally encountered as the tetrahydrate, [Be(H 2 O) 4]SO 4 is a white crystalline solid. It was first isolated in 1815 by Jons Jakob Berzelius. [4] Beryllium sulfate may be prepared by treating an aqueous solution of many beryllium salts with sulfuric acid, followed by evaporation
The table below lists producers and suppliers of Beryllium sulfate as a commercial chemical for laboratories, research, industry and production with the corresponding contact details.
Beryllium and its inorganic compounds are usually not metabolized and are mainly eliminated with urine and also with faeces. Acute beryllium disease occurs after inhalation exposure to high beryllium concen-trations (> 100 μg/m3) and is characterized by symptoms of acute pneumonitis.
In all of these cases, the theoretical yield of product is determined by the limiting reactant in the reaction, and some of the excess reactant is left over. If aluminum and chlorine gas, a diatomic gas, react to form aluminum chloride according to the equation shown below, 2 Al (s) + 3 Cl 2 (g) → 2 AlCl 3 (s)
In this evaluation only soluble inorganic and non-radioactive beryllium (9Be) salts are considered in relation to an estimation of a health based quality criterion in drinking water. This evaluation is based on reviews and evaluations published by ATSDR (2002), WHO (1990) and US-EPA (IRIS 2008).
Learning Objectives. By the end of this section, you will be able to: Define ionic and molecular (covalent) compounds. Predict the type of compound formed from elements based on their location within the periodic table. Determine formulas for simple ionic compounds.
The original Kjellgren process proceeded to separate aluminum and other impurities from beryllium by a series of crystal-lization and precipitation steps. Materion's practice today is to introduce the aluminum-beryllium sulfate solution into the
