3. For an aqueous solution of a given electrolyte:
- write the equations of the processes that take place on the electrodes during electrolysis;
- calculate how much and what substances will be released on the cathode and anode if the electrolysis is carried out at a current strength equal to I = .... A, for t hours and a current output of W;
- determine how the environment at the anode and cathode will change during electrolysis
- determine how the anode process will change if the anode is replaced with another one indicated in the table:
Electrolyte Electrodes W I, A t.4 Replacement
MnCl2 copper 0.9 10 2.5 graphite
