Problem 18.64

Industrially, copper metal can be purified electrolytically according to the following arrangement. The anode is made of the impure Cu electrode and the cathode is the pure Cu electrode. The electrodes are immersed in a CuSO4 solution. (a) Write the half-cell reactions at the electrodes. (b) Calculate the mass (in g) of Cu purified after passing a current of 20 A for 10 h. (c) Explain why impurities such as Zn, Fe, Au, and Ag are not deposited at the electrodes. Pure copper cathode Cu2+ SO4 2 Impure copper anode Battery

Chapter 11: Pure Competition in the Long Run  The long run in pure competition o Firms can expand or contract capacity o Firms can enter or exit the industry  Profit maximization in the long run o Easy entry and exit  The only long run adjustment we consider o Identical costs  All firms in the industry have identical costs o Constant cost industry- entry and exit of firms do not affect resource prices  Long run adjustment process o Adjustment process in pure competition  Firms seek profits and shun losses  Firms are free to enter or to exit  Production will occur at firm’s minimum average total cost  Price will equal minimum average total cost  Long run equilibrium o Entry eliminates profit  Firms enter  Supply increases  Price falls o Exit eliminates losses  Firms leave  Supply decreases  Price rises  Long run supply curves o Constant cost industry  Entry/exit does not affect long run ATC  Constant resource prices  Special case o Increasing cost industry  Most industries  Long run ATC increases with expansion  Specialized resources o Decreasing cost industry  Lower costs as industry expands  Pure competition and efficiency o In the long run, efficiency is achieved o Productive efficienc
