The complex that dissolves in water is

Options

  1. ANH 4 3 As Mo 3 O 10 4
  2. BFe 4 Fe ( CN ) 6 3
  3. CK 3 Co NO 2 6
  4. DFe 3 ( OH ) 2 ( OAc ) 6 Cl

Correct answer

D. Fe 3 ( OH ) 2 ( OAc ) 6 Cl

Step-by-step solution

Fe 3 ( OH ) 2 ( OAc ) 6 Cl is a coordination complex containing iron ions coordinated with hydroxide and acetate ligands. When dissolved in water, this complex can undergo hydrolysis and dissociation. So, Fe 3 ( OH ) 2 ( OAc ) 6 Cl dissolves in water. Rest of the complexes form precipitate.
