A voltaic cell consists of two half-cells. One of the half-cells contains a platinum electrode surrounded by chromium (III) and dichromate ions. 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: (a) Write the cell diagram notation (b) Calculate E° for the cell (c) Calculate the voltage of the cell when all ionic species except H+ are 0.1500M and the pH is at -0.30

Question
A voltaic cell consists of two half-cells. One of the half-cells contains a platinum electrode surrounded
by chromium (III) and dichromate ions. 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:
(a) Write the cell diagram notation
(b) Calculate E° for the cell
(c) Calculate the voltage of the cell when all ionic species except H+ are 0.1500M and the pH is at -0.30
