JEE MainChemistrySalt AnalysisMCQ+4 / −1
When a salt is treated with sodium hydroxide solution it gives gas X . On passing gas X through reagent Y a brown coloured precipitate is formed. X and Y respectively, are
  1. A
    X=NH3\mathrm{X}=\mathrm{NH}_3X=NH3​ and Y=HgO\mathrm{Y}=\mathrm{HgO}Y=HgO
  2. B
    X=NH4Cl\mathrm{X}=\mathrm{NH}_4 \mathrm{Cl}X=NH4​Cl and Y=KOH\mathrm{Y}=\mathrm{KOH}Y=KOH
  3. C
    X=NH3\mathrm{X}=\mathrm{NH}_3X=NH3​ and Y=K2HgI4+KOH\mathrm{Y}=\mathrm{K}_2 \mathrm{HgI}_4+\mathrm{KOH}Y=K2​HgI4​+KOH
  4. D
    X=HCl\mathrm{X}=\mathrm{HCl}X=HCl and Y=NH4Cl\mathrm{Y}=\mathrm{NH}_4 \mathrm{Cl}Y=NH4​Cl
