Copper is the most noble of the first row transition metals and occurs in small deposits in several countries. Ores of copperinclude 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 involves partial roasting, removal of iron and self-reduction.
The concentration of potassiumions inside a biological cell is at least twenty times higher than the outside. The resulting potential difference across the cell is important in several processes such as transmission of nerve impulses and maintaining the ion balance. A simple model for such a concentration cell involving a metal M is:
$$M(s)\mid M^{+}(aq; 0.05 molar)\mid \mid M^{+}(aq; 1 molar)\mid M(s)$$
For the above electrolytic cell the magnitude of the cell potential $$\mid E_{cell}\mid=70 mV$$.
