Do the electrodes in an electrolytic cell have fixed polarity like a battery?

In an electrolytic cell, the flow of electrons is form

What will be pH of aqueous solution of electrolyte in electrolytic cell during electrolysis of CuSO_4 (aq) between graphite electrodes ?

The resistance of a N//10 KCI solution is 245 ohms. Calculate the specific conductance and the equivalent conductance of the solution if the electrodes in the cell are 4 cm apart and each having an area of 7.0 sq cm.

After electrlysis of NaCI solution with inert electrodes for a certain period of time 600mL of the solution was left. Which was found to be 1N in NaOH . During the same time, 31.75 g of Cu deposited in the copper voltameter in series the electrolytic cell. calculate the percentage yield of NaOH obtained.
