Sketch the galvanic cells based on the following half-reactions. Calculate ϐo, show the direction of electron flow and the direction of ion migration through the salt bridge, identify the cathode and anode, and give the overall balanced equation. Assume that all concentrations are 1.0 M and that all partial pressures are 1.0 atm.
Answer to relevant QuestionsWhat volumes of H2(g) and O2(g) at STP are produced from the electrolysis of water by a current of 2.50 A in 15.0 min? What is the maximum work that can be obtained from a hydrogen– oxygen fuel cell at standard conditions that produces 1.00 kg of water at 25oC? Why do we say that this is the maximum work that can be obtained? What are the ...A standard galvanic cell is constructed so that the overall cell reaction is 2Al3+(aq) + 3M(s) → 3M2+(aq) + 2Al(s) where M is an unknown metal. If ΔGo = –411 kJ for the overall cell reaction, identify the metal used ...The measurement of F- ion concentration by ion-selective electrodes at 25.00oC obeys the equation ϐmeas = ϐref – 0.05916 log[F–] This exercise requires students to formulate the “rules of thumb” that managers could use to implement a “management by exception” approach to managing variances.
