alleryWhich is **not** a feature of a **double salt**?
ADissociates completely into simple ions in water
BHas a definite stoichiometric ratio
CLoses identity in solution
DRetains its complex ion in solution
Answer & Solution
Correct answer: D. Retains its complex ion in solution
Double salts (e.g. Mohr's salt FeSO₄·(NH₄)₂SO₄·6H₂O) lose identity in solution — they dissociate fully into all constituent simple ions.
Coordination compounds, in contrast, retain at least one complex ion in solution.
