An electrochemical cell consists of a standard hydrogen electrode and a copper metal electrode.
Answer to relevant QuestionsSketch the galvanic cells based on the following overall 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 ...Why is the electrolysis of molten salts much easier to predict in terms of what occurs at the anode and cathode than the electrolysis of aqueous dissolved salts? It takes 15 kWh (kilowatt hours) of electrical energy to produce 1.0 kg of aluminum metal from aluminum oxide by the Hall–Heroult process. Compare this value with the amount of energy necessary to melt 1.0 kg of aluminum ...The overall reaction and standard cell potential at 25oC for the rechargeable nickel–cadmium alkaline battery is Cd(s) + NiO2(s) + 2H2O(l) → Ni(OH)2(s) + Cd(OH)2(s) ϐo = 1.10 V For every mole of Cd consumed in the ...The measurement of pH using a glass electrode obeys the Nernst equation. The typical response of a pH meter at 25.00oC is given by the equation ϐmeas = ϐ ref 1 0.05916 pH where ϐref contains the potential of the reference ...
