Match the following mixtures with the respective solution used for their separation:
Species | Solution used for separation |
|---|---|
(a) N2 and CO | (i) water |
(b) N2 and O2 | (ii) H2SO4 |
(c) N2 and NH3 | (iii) Ammonical Cu2Cl2 |
(d) PH3 and NH3 | (iv) Pyrogallol |
Options:
Answer:
B
Solution:
The correct matching is:
(a) N₂ and CO - (iii) Ammonical CuCl
(b) N₂ and O₂ - (iv) Pyrogallol
(c) N₂ and NH₃ - (ii) H₂SO₄
(d) PH₃ and NH₃ - (i) water
Explanation:
CO is absorbed by ammonical CuCl. O₂ is absorbed by pyrogallol. NH₃ reacts with H₂SO₄ to form ammonium sulphate. PH₃ is less soluble in water than NH₃, allowing for separation via selective dissolution. The key concept is selective absorption or reaction based on the chemical properties of the gases.
