1. A student constructed a voltaic cell using nickel and lead as electrodes. He also used 0.50 M Ni(NO3)2 as the anolyte and 0.25 M Pb(NO3)₂2 as the catholyte. Ni2+ (aq) +2e → Nis), Ered= -0.25 V Pb²+ (aq) + 2e → Pb(s), Eºred = -0.13 V A. Write the balanced reaction occurring in the voltaic cell. Write your answers in your solution sheet. B. Compute the standard cell potential, Eºcell. C. Calculate the cell potential at 28 °C, Ecell- D. If the concentration of Pb(NO3)2 solution used was increased, what will be the effect on the measured potential? (increase, decrease, no effect)
