P b + d i l . HN O 3 → W a r m P + Q ↑ + H 2 O incorrect statement for Q is

Options

  1. AParamagnetic colourless gas
  2. BIt is oxidized to paramagnetic coloured gas by air
  3. CIt combines with F e 2 ( S O 4 ) 3
  4. DIt is also obtained by disproportionation of H N O 2

Correct answer

C. It combines with F e 2 ( S O 4 ) 3

Step-by-step solution

Here only statement in option C is incorrect as it combines with F e S O 4 and not it combines with F e 2 ( S O 4 ) 3 Pb + dil . HNO 3 → Warm Pb(NO 3 ) 2 + NO ↑ + H 2 O paramagnetic, coloured gas H N O 2 → H N O 3 + N O ↑ + H 2 O
