JEE AdvancedChemistryP Block ElementsMultiple correct+4 / −2
A solution of colourless salt H on boiling with excess NaOH produces a non-flammable gas. The gas evolution ceases after sometime. Upon addition of Zn dust to the same solution, the gas evolution restarts. The colourless salt(s) H is(are):
  1. A
    NH 4{}_44​ NO 3{}_33​
  2. B
    NH 4{}_44​ NO 2{}_22​
  3. C
    NH 4{}_44​ Cl
  4. D
    (NH 4{}_44​) 2{}_22​ SO 4{}_44​
