Question

Oxygen Supply in Submarines Nuclear submarines can stay under water nearly indefinitely because they can produce their own oxygen by electrolysis of water.

How many liters of O2 at 298 K and 1.00 bar are produced in 1.00 hr in an electrolytic cell operating at a current of 0.0200 A?

Answer 1

1.865 * 10^-4 L

Step-by-step explanation:

The equation of the reaction is:

4OH^-(aq) ----->2H2O(l) + O2(g) + 4e

Since one mole of oxygen which occupies 22.4 L is produced in the electrolysis of water by 4 Faraday of electricity as shown in the equation above;

Then;

4 * 96500 C liberates 22.4 L of oxygen

60 * 60 * 0.0200 C will liberate 60 * 60 * 0.0200 * 22.4/4 * 96500

= 1.865 * 10^-4 L
