Double salts definition in co-ordination chemistry

When two or more in stoichimetric proportions are attached to each other, resulting in the formation of a molecular salt which exist only in solid crystal state but
dissociate into their constituent compound in water or any other , then this type of molecular compound is called double salt.

Double salt examples.

Double salt compounds is a type of molecular compound or higher order compound which produced from compounds.

There are many man made as well as natural occurring well known double salt compounds in . Such as Carnallite, potash alum Mohr’s salt etc.

If a solution of ferrous sulfate and ammonium sulfate in their stoichimetric proportions are allowed to evaporate, then a light green color molecular compound, ferrous ammonium sulfate hexahydrate with FeSO4, (NH4)2 SO4, 6H2O is obtained.

The resulting double salt is also known as Mohr’s salt. In the similar way, potash alum is made from the stoichimetric proportions of and potassium sulfate salt.

On the other hand, naturally occurring double salt, carnallite consist of potassium chloride and magnesium chloride.

Double salt compound properties.

( II ) Double salt can only exist in

( III ) They are completely ionize in aqueous solution or any other solvents.

(IV ) Double salts are soluble in water.

(V) They do not exhibit .

( VI ) Each double salt molecule contains one or more crystal water molecule .
