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: 2BFO, -(ag) + 12н*(аq) + 10е- — Brz(1) + 6H,0 E = 1.478 V (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-0.301.
