Corrosion of Copper Pipes Copper is frequently the material of choice for household plumbing. In some communities heavily chlorinated water corrodes copper pipes. The corrosion reaction is believed to involve the formation of copper(I) chloride: 2 Cu(s) + C(aq) 2 CuCl(s) a. Write balanced equations for the half-reactions in this redox reaction. Include the phases of all species in the chemical equations. b. Calculate Erxn and AGxn for the reaction. Ered for Cut (aq) is 0.521 V. Ered for Cl2(g) is 1.3583 V. Number E rxn Number v AG = rxn kJ
