Q. $(X) K O H (Y)$ (gas turns red litmus blue) $+ (Z)$
$Z n + K O H (Y) (gas) . (X) Δ$ gas (does not support combustion)
Identify $(X)$ to $(Z)$ :

$X = N H_{4} NO_{2} Y = N H_{3} Z = K NO_{2}$

$X = (N H)_{4})_{2} (C r)_{2} (O)_{7} Y = (N H)_{3} Z = (C r)_{2} (O)_{3}$

$X = (N H_{4})_{2} (SO)_{4} Y = (N H)_{3} Z = (K)_{2} (SO)_{4}$

$X = N H_{4} NO_{3} Y = N H_{3} Z = K NO_{3}$

$(X) (N H)_{4} (NO)_{2} + K O H \to (Y) (N H)_{3} ↑ + (Z) (K NO)_{2} + (H)_{2} O$
$(Z) N O_{2}^{-} + 3 Z n + 5 (O H)^{-} + 5 (H)_{2} O \to soluble 3 ([Z n (O H)_{4}])^{2 -} + (Y) (N H)_{3} ↑$
