Differences between Double salt and Complex Compound Preparation and Properties
Differences between double Salt and a Complex Compound (Coordination Compound) :
Double Salt | Complex Compound |
Double salt exists only in solid state and dissociate into ions in aqueous solution or in any other solvent. | Co-ordination compounds exist in the solid state as well as when dissolved in water or any other solvent. |
In solution, they lose their identity. | They do not completely lose their identity in solution. |
The properties of the double salt are essentially the same as those of constituent compounds. | The properties of coordination compound are different from the constituents. |
In a double salt, metal ions exhibit their normal valiancy.
|
In co-ordination compound, metal ion is surrounded by a number of positively charged ions or neutral molecules more than its normal valency. |
