Mathematics · Electrochemistry Calculation
At 298 K, a galvanic cell comprises a zinc electrode submerged in an acidic 0.9 M Zn2+ solution, connected via a salt bridge to a 0.3 M Ag+ solution containing a silver electrode. Given the standard reduction potentials E°(Zn2+/Zn) = -0.76 V and E°(Ag+/Ag) = +0.80 V versus SHE, determine the initial electromotive force (emf) of the cell at 298 K.
