From the Pourbaix diagram of Cu shown below 1.6 1.2+ 2 C Cu(OH),(s) 0.8 0.4 3 Cu,0(s) Cuof -0.4 + Cu(s) -0.8 + 1.2 -2 12 16 PH a.) predict the reactions 1-3 as a.) acid-base reaction and c.) both acid-base and red-ox reactions b.) red-ox reaction b.) predict the reactions involved in 1-3. c.) predict the reaction of Cu with H2 below the H2 line, this is where the Cu is unstable in contact with H,0 (identify the product of the reaction when Cu reacts with water) d.) Cu is also unstable in air-saturated water, where the potential is close to the 0, line . Predict the reactions here. 1, A/ 43
