52. Solving a chemistry problem

405.1. Draw a diagram of the electrolysis of a salt solution. Write the electrode equations for the processes occurring on the electrodes. Confirm the cathodic process by calculations.
2. Calculate the mass or (and) volume (under normal conditions for gases) of products released on the electrodes when a current of force I (A) is passed through the solution over time (t)
