Based on epirical evidence, it should be the nitrate ion as they all decompose on heating.

but isnt the one with the higher charge usually easier to distort? annnd sorry i meant CO3^2- instead of sulphate

As I stated, based on EMPIRICAL evidence ..

Indeed carbonates usually decompose on heating (apart from group 1 below Li). Of course, decomposition is also influenced by other factors, such as the volatility of the products, although both carbonates and nitrates produce gases on heating.

But the fact is that ALL nitrates decompose, whereas not all carbonates decompose thermally.

what i dont understand is why is it easier to decompose nitrates when they have a charge of -1.. carbonates have a charge of -2 arent they supposed to be decompsed more easily by the polarisation of group 1 metals.. why can group 1 metals polarise nitrates and not carbonates
