Answer: Option i)
Because of the smaller cation and larger anion sizes (smaller cation stabilises smaller anion through crystal lattice energy), Beryllium Carbonate can only be preserved in CO2 atmosphere.
Which of the carbonates given below is unstable in air and is kept in CO2 atmosphere to avoid decomposition. (i) BeCO3 (ii) MgCO3 (iii) CaCO3 (iv) BaCO3
