Copper is the most noble of the first row transition metals and occurs in small deposits in several countries. Ores of copper include chalcanthite `(CuSO_(4).5H_(2)O)` atacamite `(Cu_(2)Cl(OH)_(3))`,Cuprite `(Cu_(2)O)` , copper glance `(Cu_(2)S)` and malachite `(Cu_(2)(OH)_(2)CO_(3))`. however 80% of the world copper production comes from the ore chalcopyrite `(CuFeS_2)`. the extraction of copper from chalcopyrite invovles partial roasting . removal of iron and self-reduction.
IF the 0.05 molar solution of `M^(+)` is replaced by a 0.0025 molar `M^(+)` solution. then the magnitude of the cell potential would be
