1. The magnitudes of the standard electrode potentials of two
metals, A and B, are(1) A2+ + 2e- →A |E°| = 0.63V (2) B2+ + 2e- →B
|E°| = 1.24V Where the | | notation denotes that only the magnitude
(but not the sign) of the E° value is shown. When half-reactions
(1) and (2) are connected, electrons flow spontaneously from
half-reaction (1) to half-reaction (2). When half-reaction (1) is
connected to a standard hydrogen electrode (H+=H2), electrons flow
spontaneously...

Standard potentials are measured against the standard hydrogen electrode (SHE). Because it is not always convenient to use a S.Н.Е., often other reference electrodes are used. The saturated calomel electrode (SCE.) is one commonly used reference electrode, with a reduction potential of +0.242 V versus the S.H.E. Using a table of standard reductions, determine what the standard reduction potential of each reduction half-reaction would be versus the S.C.E Cl2 (g) + 2e-→ 2 Cl-(aq) E1.36 Fe3 + (aq) + 3...

2. You measured cell potentials (voltages) for reactions of metals and metal ions. We will use the standard date and practice calculating these. Recall: E-Ecathode - Eanode Remember reduction occurs at the cathode; oxidation occurs at the anode For the anode reactions, your reactant will be on the product side of the standard equation, but don't change any sign. The equation does that for you. Cathode Reaction Agt + e → Ag Ecathode Anode Reaction...
