Introduction
beryllium sulfate tetrahydrate is a colorless tetragonal crystal. the production method is to slowly add Be(OH)2 powder to dilute sulfuric acid, dissolve it under stirring until it is no longer dissolved, filter, add a small amount of sulfuric acid to the filtrate, acidify and evaporate and concentrate. Cool to room temperature, and air dry at room temperature after the crystallization is drained. This crystal is beryllium sulfate tetrahydrate.
application
Beryllium sulfate tetrahydrate can be used to study the chelation of beryllium and dicarboxylic acid esters to understand the physiology and chemistry of beryllium.
