Cu half reaction

WebAnswer (1 of 2): It is very simple question. Copper mostly occur in +1 (called cuprous) or +2 (called cupric) oxidation state. By seeing one glance you can say it is +1. … WebWhen the two half-reactions are added, we get: 2Ag + + 2e¯ + Cu ---> 2Ag + Cu 2+ + 2e¯ With two electrons on each side, they may be canceled, resulting in: 2Ag + + Cu ---> 2Ag + Cu 2+ This is the correct answer. Notice that there are two silvers on each side and one copper. Notice also that the total charge on each side is +2. It is balanced ...
