Question

Copper is the most noble of the first row transition metals and occurs in small deposits in several countries. Ores of copper include chalcanthite

(C u S O_{4} .5 H_{2} O)

atacamite

(C u_{2} C l (O H)_{3})

,Cuprite

(C u_{2} O)

, copper glance

(C u_{2} S)

and malachite

(C u_{2} (O H)_{2} C O_{3})

. however 80% of the world copper production comes from the ore chalcopyrite

(C u F e S_{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
