A concentration cell consists of two half-cells with identical electrodes but different ion concentrations. Consider the following concentration cell (pictured below). M(s) | M*(satd MX) || M*(0.100 M)| M(s) Ecell = 0.417 V At the anode, a metal electrode (M) is placed in a saturated aqueous solution containing ions of the same metal (M) and a halogen (X), MX. At the cathode, a second electrode of the same metal (M) is placed in a solution with [M*] = 0.100 M.The two half-cells are connected by a salt bridge, and the measured cell voltage is 0.417 V. The cell reaction occurring in this concentration cell is Reduction: M*(0.100 M) + e → M(s) Oxidation: M(s) → M*(satd MX) + e From this information, calculate the Ksp of MX. NOTE: You may enter a number in scientific notation as: 6.6E-66 or 6.66*10^-66 or 6.66x10^-66 (DO NOT ADD Spaces) Anode MX(s) MX (sat'd aq) 0.417 Voltmeter Salt bridge KNO,(aq) M Cathode M*(0.100M)
