CuSO4. K2SO4 is *
(a) acid salt
(b) a mixed salt
(c) normal salt
(d) double salt

Answer:
Double salts are addition compounds formed by the combination of two or more stable compounds in stoichiometric proportions. Carnallite is a double salt formed when KCl and MgCl

Answer:
(d) double salt
CuSO. K2SO
is double salt.
Explanation:
A salt that has two different cations or anion types is referred to as a double salt. Alums and Tutton's salts are two examples of double salts. Alums have the general formula MIMIII[SO4]212H2O, while Tutton's salts have [MI]2MII[SO4]26H2O. Other examples include potassium sodium tartrate, bromlite BaCa(CO3)2, and ammonium iron sulphate. Fluoride and carbonate anions are both present in fluoro carbonates. Coordination complexes that form double salts are common.
Complexes shouldn't be confused with double salts. Only the solid contains double salts. A double salt behaves as a combination of the two distinct salts when dissolved in water; unlike a hexaquark complex, which does not completely dissociate into simple ions; the complex ion remains unchanged.
CuSO4. K2SO4 is Double salts are distinct from mixed-crystal systems where two salts crystallize; the latter is a mixture, whereas the former involves a chemical combination with fixed composition. In general, the properties of the formed double salt will differ from those of the single salts that made it up.
