Q9(a). Thermal decomposition of Li, Mg and Na salts; diagonal relationship
What happens when the following salts are strongly heated? Give balanced equations: (i) Li₂CO₃ (ii) LiNO₃ (iii) MgCO₃ (iv) Mg(NO₃)₂ (v) NaNO₃ (vi) Na₂CO₃. From these reactions, can you suggest (with reasons) a relationship between any two of these metal ions? Suggest one more property in favour of this relationship.
