Cu half reaction
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 ... WebJun 22, 2024 · The electrochemical cell consists of two "half-cells" that correspond to each of the above half-cell reactions. For the half-cell corresponding to the oxidation reaction, a strip of Zn metal is placed in a solution of Zn 2+ ions. For the reduction half-cell, a strip of Cu metal is placed in a solution of Cu 2+ ions. We then connect these cells ...

WebMay 27, 2024 · A reaction between copper metal and hydrochloric acid would go something like this: C u + 2 H C l C u C l X 2 + H X 2 ...which we can write as: C u + 2 H X + C u X 2 + + H X 2 If we break this up into half reactions, we get: C u 2 e X − + C u E ° = − 0.34 V 2 H X + + 2 e X − H X 2 E ° = 0.00 V WebAlthough the sum of these two half-reactions gives the desired half-reaction, we cannot simply add the potentials of two reductive half-reactions to obtain the potential of a third reductive half-reaction because \(E^o\) is not a state function. However, because \(ΔG^o\) is a state function, the sum of the \(ΔG^o\) values for the individual ...
WebAssume that the Cu2+ + 2e - Cu half reaction has an electrode potential of 0.34 volts as indicated on the line scale below (1 division = 0.1 volt).
