3. For an aqueous solution of this electrolyte:
- write the equations of the processes that occur on the electrodes during electrolysis;
- calculate how much 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 t hours and a current output of W, at pH = 11;
- determine how the environment at the anode and cathode will change during the electrolysis process
- determine how the anodic process will change if the anode is replaced with another one indicated in the table:
Electrolyte Electrodes watt I, A t, h Replacement
Cu(NO3)2 copper 0.85 25 0.5 graphite
