Solution

The correct options are
A $A g^{+}$ forms complexes, $N a^{+}$ does not.
B $N a_{2} C O_{3}$ is thermally stable while $A g_{2} C O_{3}$ decomposes into Ag, $C O_{2}$ and $O_{2}$ .
D NaCl is water soluble , AgCl is insoluble.
$2 A g C O_{3} (s) \to 2 A g (s) + 2 C O_{2} (g) + O (g)$ and $N a_{2} C O_{3}$ is thermally stable.

$A g^{+}$ forms complexes like $A g (C N)_{2}^{-}$ , $N a^{+}$ does not.

NaCl golden yellow flame.
AgCl no flame.
