Question

Lithium Carbonate is less stable than Sodium Carbonate *​

Answer 1

Answer:

Therefore, the small size lithium ion polarizes large size carbonate ions which forms more stable lithium oxide. Hence, lithium carbonate requires very low temperature for decomposition reaction and sodium carbonate requires very high temperature for decomposition reaction.

Answer 2

Lithium Carbonate is less stable than Sodium Carbonate.

• The stability of all the carbonates of alkali metals is quite good. Lithium carbonate is the only exception. This is the reason for the decomposition of Lithium carbonate at a lower temperature while Sodium Carbonate decomposes at a higher temperature.
• Being very small, Lithium polarises a large CO3²- ion and leads to form more stable Li2O and CO2.
