Vedclass · Answer

(C) . $BeCO_3$ has the lowest thermal stability among alkaline earth metal carbonates. It decomposes to give $BeO$ and $CO_2$. Hence,it is stored in an atmosphere of $CO_2$ to prevent decomposition. This statement is correct.$B$. $Be$ is amphoteric and dissolves in alkali to form the beryllate ion: $Be + 2OH^- + 2H_2O \rightarrow [Be(OH)_4]^{2-} + H_2$. This statement is correct.$C$ and $D$. $BeF_2$ reacts with $NaF$ to form the complex $Na_2[BeF_4]$. In this complex,$Be$ is part of the complex anion $[BeF_4]^{2-}$. Therefore,the statement that $Be$ goes with the cation is incorrect,and the statement that $Be$ goes with the anion is correct.
