Ti + Zn2+ Ti2+ + Zn 2Lu + 3Ti2+ 2Lu3+ + 3Ti Predict whether each of the following reactions will occur: a) Pb + Ti2+ Pb2+ + Ti b) 2Lu + 3Pb2+ 2Lu3+ + 3Pb c) 2Lu3+ + 3Zn 3Zn2+ + 2Lu 9. The metals Rh, Ti, Cr, and Pd are individually placed in 1.0M solutions of Rh2+, Ti2+, Cr2+, and Pd2+ , and the cell voltages of the spontaneous reactions are determined. a) Arrange the metals in order of increasing strength as reducing agents. b) Determine the cell voltage for Ti in a 1.0M solution of Cr2+ . 10. Hebden p. 225 #38, 40-41 XIV) Selecting Preferred Reactions In many reaction environments, there’s more than one substance that can reduce, and/or more than one substance that can oxidize. How can you determine the reaction that actually occurs? 1. When several different reductions can occur, 2. When several different oxidations can occur, Write the redox equation that will occur for the following cell: A method to deduce the actual reaction occurring: i) List all possible oxidizing agents reducing agents
