Question

&ldquo; A &rdquo; obtained by Ostwald's method involving air oxidation of NH 3 , upon further air oxidation produces &ldquo; B &rdquo;. &ldquo; B &rdquo; on hydration forms an oxoacid of Nitrogen along with evolution of &ldquo; A &rdquo;. The oxoacid also produces &ldquo; A &rdquo; and gives positive brown ring test

Correct answer: C. NO , &#160; NO 2

Ostwald's method is based upon catalytic oxidation of NH 3 by atmospheric oxygen. 4 NH 3 &#160; ( g ) &#160; + 5 O 2 &#160; ( g ) &#160; &#8594; 500 K , &#160; 9 &#160; bar Pt / Rh &#160; gauge &#160; catalyst &#160; 4 NO &#160; ( g ) &#160; ( A ) + 6 H 2 O &#160; ( g ) Nitric oxide thus formed combines with oxygen giving NO 2 . 2 NO &#160; ( g ) &#160; + O 2 &#160; ( g ) &#160; &#8652; &#160; 2 NO 2 &#160; ( g ) ( B ) Nitrogen dioxide so formed, dissolves in water to give HNO 3 . 3 NO 2 &#160; ( g ) &#160; + &
