Level: AP Chemistry · Curriculum: AP Chem Unit 9
At which electrode does oxidation occur in every electrochemical cell? What is E°cell for a cell made from Mg²⁺/Mg (−2.37 V) and Ag⁺/Ag (+0.80 V)? What is the sign of the anode in an electrolytic cell? A cell with n = 2 and E°cell = 0.50 V has what value of ΔG°? How many moles of electrons are carried by 3860 C of charge? For Q less than 1 in a standard cell, how does E compare with E°? What is the main job of a salt bridge? Which metal makes the best sacrificial anode for iron (E° −0.44 V)? What are the values of E and Q at equilibrium in a galvanic cell? What forms at the cathode in the electrolysis of concentrated aqueous NaCl? What happens at the anode? — Oxidation, in every cell. What happens at the cathode? — Reduction, in every cell. Formula for standard cell potential? — E°cell = E°cathode − E°anode Relation between ΔG° and E°? — ΔG° = −nFE°cell Value of the Faraday constant? — F = 96 485 C/mol of electrons Sign of the anode in a galvanic cell? — Negative Sign of the anode in an electrolytic cell? — Positive Nernst equation at 25 °C? — E = E° − (0.0592/n) log Q Link between charge, current and time? — Q = I t What is E at equilibrium? — Zero, because Q = K Keep going with Lina
