A voltaic cell consists of two half-cells. One of the half-cells contains a platinum electrode surrounded by chromium (III) and dichromate The other half-cell contains a platinum electrode surrounded by bromate ions and liquid bromine. Assume that the cell reaction, which produces a positive voltage, involves both chromium (III) and bromate ions. The cell is at 25°C. Information for the bromate reduction half-reaction is as follows: 2BrO3-(aq)+12H+(aq)+10e-----> Br2(l)+H2O Eored=1.478 V Calculate the voltage of the cell when all ionic species except H+ are 1500M and the pH is at -0.301.
