Here is a precise problem for the student to solve:A copper electrode is placed in a solution of copper nitrate with a concentration of 0.1 M, while a platinum electrode is placed in a solution of hydrogen peroxide. The potential difference of the half-reactions for the copper/copper(II) and hydrogen peroxide/water couples are +0.34 V and +1.77 V, respectively. Calculate the current density (in A/m²) at the copper electrode when a current of 0.25 A is passed through the cell for 10 minutes.
