Many hexaaqua complex ions can undergo reaction with water as given below[Fe(H2O)6]+2 aq + H2O⇌[Fe(H2O)5OH]+ + H3O+The reaction is classed as:
Correct answer: D. Decomposition reaction
- A. Redox reaction
- B. Acid base reaction
- C. Substitution reaction
- D. Decomposition reaction
Explanation
The reaction is 'decomposition' as one mole of water is removed to form the hydronium ion

About Bronsted-Lowry and Lewis Concepts
The Brønsted-Lowry concept defines acids as proton donors and bases as proton acceptors, producing conjugate acid-base pairs. The Lewis concept extends the idea to electron-pair acceptors and donors, so compounds such as BF3 and NH3 can be treated as acid and base even without proton transfer, unlike the Arrhenius definition.
