Question
The correct order of thermal stability of the following metal carbonates is ans. BeCO3 < MgCO3 < CaCO3 < BaCO3
BaCO3 < CaCO3 < MgCO3 < BeCO3
BaCO3 < BeCO3 < MgCO3 < CaCO3
MgCO3 < CaCO3 < BaCO3 < BeCO3
Solution
The correct order of thermal stability of the following metal carbonates is BeCO3 < MgCO3 < CaCO3 < BaCO3.
This order is based on the size of the cations (Be2+, Mg2+, Ca2+, Ba2+). As the size of the cation increases, the thermal stability of the carbonate also increases. This is because larger cations can stabilize the larger carbonate anion (CO3 2-) better than smaller cations.
So, the correct order is BeCO3 < MgCO3 < CaCO3 < BaCO3.
