A, B, C cannot be distinguished by
Options:
Answer:
C
Solution:
The complexes A, B, and C differ in the number of ionizable Cl⁻ ions outside the coordination sphere (3, 2, and 1 respectively). Hence, they can be distinguished by electrical conductivity and by quantitative precipitation with AgNO₃, as different amounts of AgCl are formed. They can also be distinguished by weight loss with concentrated H₂SO₄ because they contain different numbers of water molecules. However, BaCl₂ does not give any characteristic difference, since chloride ions do not form an insoluble precipitate with Ba²⁺.
Answer: (c) BaCl₂ solution
