a. The half reactions

b. Flow of electrons

c. Short-form notation

d. Electric potential (voltage)

Balance the following reaction in a basic solution: I^- + MnO₄^2-- → MnO₂ + I₂

Balance the following half-reaction in an acidic solution: Cr₂O₇ ^2-→ Cr³⁺

A galvanic cell is constructed by coupling Ag and Cd electrodes dipped in 0.5M silver nitrate and 0.25M CdSO₄ respectively at 25⁰ C. Write the cell scheme cell reaction, and calculate emf of the cell. Given that SRPs of Ag and Cd are +0.80V and -0.40V respectively.
