Double salts when dissolved in water dissociate into simple ions completely while complexes do not dissociate into simple ions and maintain the property of complexes. Or in other words we can say that double salt is a salt that crystallizes as a single substance but ionizes as two distinct salts when dissolved. (a) Mixed salt. Double salts should not be confused with complexes.When dissolved in water, a double salt completely dissociates into simple ions while a hexaaquo complex does not; the complex ion remains unchanged. Al 2 (SO 4) 3.24H 2 O ( potash Alum), (NH 4) 2 Al 2 (SO 4) 3.24H 2 O (Ammonium Alum) FeSO 4 (NH 4) 2 SO 4.6H 2 O (Mohr’s Salt) There must be either two cationic components or two anionic components, and the two salts must be capable of crystallizing together in regular fashion. An example of double salt i... chemistry. Because it is capable of deprotonating water and yielding a basic solution, sodium bicarbonate is a basic salt. The complex ion is acting as an acid by donating a hydrogen ion to water molecules in the solution. It is a common laboratory reagent. For example, the sodium salt form of an oral hypoglycaemic agent tolbutamide is known to dissolve 5,000 times faster in acidic media if compared to the free acid. Similarly, K 4 [YbI 6] is a complex salt and contains the discrete [YbI 6] 4− ion, which remains intact in aqueous solutions. However, on dissolving in water, it furnishes one simple ion and another complex ion. Examples: The compounds like Potash Alum [K 2 S0 4 . Potassium ferrocyanide is an example for 1) Complex salts 2) Normal salts 3) Double salts 4) Basic salts 2. 3 Answer(s) Available.
