- Consider the following galvanic cell: Calculate the concentrations of Ag+(aq) and Ni2+(aq) once the cell is dead.arrow_forwardConsider a cell based on the following half-reactions: a. Draw this cell under standard conditions, labeling the anode, the cathode, the direction of electron flow, and the concentrations, as appropriate. b. When enough NaCl(s) is added to the compartment containing gold to make the [Cl] = 0.10 M, the cell potential is observed to be 0.31 V. Assume that Au3+ is reduced and assume that the reaction in the compartment containing gold is Au3+(aq)+4Cl(aq)AuCl4(aq) Calculate the value of K for this reaction at 25C.arrow_forwardUsing Table 17.1, arrange the following reducing agents in order of increasing strength. Br- Zn Co PbSO4 H2S (acidic)arrow_forward
- Consider the cell described below: Al|Al3+(1.00M)||Pb2+(1.00M)|Pb Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by 0.60 mol/L. (Assume T = 25C.)arrow_forwardAn electrochemical cell consists of a nickel metal electrode immersed in a solution with [Ni2+] = 1.0 M separated by a porous disk from an aluminum metal electrode. a. What is the potential of this cell at 25C if the aluminum electrode is placed in a solution in which [Al3+] = 7.2 103 M? b. When the aluminum electrode is placed in a certain solution in which [Al3+] is unknown, the measured cell potential at 25C is 1.62 V. Calculate [Al3+] in the unknown solution. (Assume Al is oxidized.)arrow_forwardCadmium sulfide is used in some semiconductor applications. Calculate the value of the solubility product constant (Ksp) for CdS given (he following standard reduction potentials: Cds(s) + 2e Cd(s) + s2(aq) = 1.21 V Cd2+ (aq) + 2e Cd(s) = 0.402 Varrow_forward
