Solutions

Expert Solution

ans)          copper sulphate reacts   with NH4OH to form precipitate of Cu ( OH)2   WHICH   redissolves in

       excess of NH4OH forming a complex , tetramine copper sulphate.

            CuSO4   + 2 NH4OH ---------------       Cu(OH)2    +      ( NH4)2 SO4

         Cu( OH )2 + 2 ( NH4) 2 SO4    --------------------------   [ Cu ( NH3 )4 ]SO4    + 2 H2O + H2SO4

                   tetra ammine cupricsulphate known as Schwitzer's reagent is used for dissolving cellulose

in the manufacturer of artificial silk.
