Question

Why is $BeCO_{3}$ stored in carbon dioxide atmosphere ?

Answer 1

The $Be{ CO }_{ 3 }$ is stored in carbon dioxide atmosphere because under normal atmospheric condition the beryllium carbonate readily decomposes into two products namely Beryllium oxide and Carbon di oxide. When the $Be{ CO }_{ 3 }$ is placed in the atmosphere which is rich in carbon dioxide, the released carbon dioxide interacts with the atmospheric carbon dioxide and equilibrium is attained and stability is maintained. Hence, it can be inferred that in order to “prevent decomposition”, $Be{ CO }_{ 3 }$ is stored in carbon dioxide atmosphere.
