1. Lead (II) nitrate in acidic solution reacts with zinc metal to form solid lead and zinc nitrate. Balance the redox reaction between Pb(NO3)2 and Zn occurring under acidic conditions. 2. Selenium metal reacts with Chromium(III) hydroxide in basic conditions to produce chromium metal and Selenium trioxide (overall negative 2 charge when aqueous). Balance the redox reaction between Se and Cr(OH)3 occurring in basic conditions. 3. Suppose I want to want to build a voltaic cell that has a cell potential of 3.75 V what two metal/ion combinations would I use? Give the chemical reaction for this redox process. a. What half reaction would occur at the cathode and what half reaction would occur at the anode? 4. What is the difference between a voltaic cell and an electrolytic cell? 5. How do you know if a reaction is a redox reaction? 6. Is the decomposition of hydrogen peroxide from lab 9 (2H2Ozaq) → 2H2O) + O2(8) a redox reaction? Why or why not?
