3. For an aqueous solution of this electrolyte:
-write the equation of the processes that occur on the electrodes during electrolysis;
-calculate how many and what substances will be released at the cathode and anode if electrolysis is carried out at a current strength equal to I...A, for a time t, current output W;
- determine how the anodic process will change if the anode is replaced with another one indicated in the table.
CuCl2, graphite electrodes, W=0.85, I=15A, t=0.5h, zinc anode replacement, pH=4.
