1)The standard electrode potential for the reduction of Eu3+(aq) to Eu2+(aq) is ?0.43 V. determine which of the following is capable of reducing Eu3+(aq) to Eu2+(aq) under standard-state conditions? (a) Sn2+(aq) (b) ln(s) (c) HCN(aq) (d) La(s) 2)The half-cell, Tl | Tl+(1 mol L?1), is connected to a Pt | H+ | H2(1 atm) half-cell in which the concentration of H+ is unknown. The measured cell voltage is 0.0841 V and the Pt | H2 | H+ half-cell is the cathode. Standard reduction potentials are given on the next page. (a) Draw a diagram of the electrochemical cell, labeling all electrodes and solutions. (b) What is the pH in the Pt | H+ | H2 half-cell? (c) What is the value of the equilibrium constant for the reaction occurring in this cell?
