Question

In salts of polyatomic anion, as polarising power of cation increases, thermal stability of the salt decreases and decomposed species may further undergo redox reaction.
Water soluble salt (x) was heated into three products A,B and C and B and C are two different paramagnetic gases. A is red in hot condition, then salt (x) is

Solution

The correct option is D $P d (N O_{3})_{2}$
(d) $P b (N O_{3})_{2} Δ \to P b O + 2 N O_{2} + \frac{1}{2} O_{3}$
Red in hot
(Litharge) Two different
paranagentic gases
$\Rightarrow H g (N O_{3})_{2} Δ \to H g + 2 N O_{2} + O_{2}$
$\Rightarrow F e c_{2} O_{4} Δ \to F e O + C O + C O_{2}$
$\Rightarrow Z n S O_{4} > 800^{\circ} C \to Z n O + S O_{2} + \frac{1}{2} O_{2}$
