An unknown metal, M, forms divalent cations, m²+. An electrochemical cell is constructed by immersing an electrode of metallic M in 1.0 M MSO₄ (aq), connected by a salt bridge to a second half-cell of metallic silver immersed in 1.0 M AgNO₃ (aq). The electrodes are connected by a switched wire and the potential difference is measured. When the switch is closed and the cell is operating, current flows through the wire and the mass of the silver electrode increases. The net ionic equation for the reaction that occurs as the cell operates is ________. 2 Ag+ + M → 2 Ag + m²+. The measured cell potential, Ecello, is 1.49. Given the following standard reduction potentials: Reduction 1/2 Rxn Eredo (V) Ag+ + e- → Ag +0.80 V m²+ + 2 e- → M ??? Calculate the standard reduction potential of the m²+ ion. Express your answer in Volts, with two decimal places.
