Question

Which one is more stable Li_Coz or Na2CO3 ? Justify your answer.

Answer 1

Answer:

Li+ has a smaller size compared to Na+, hence polarizes the CO3- ion at a greater extent compared to Na+. Li2CO3 therefore requires less energy to break while Na2CO3 needs a higher energy making it more stable than Li2CO3. as we go down the periodic table the electropositivity of element increases.
