Description

In the experiment P3.2.5.1, a specific quantity of hydrogen is produced in an electrolysis apparatus after Hofmann to determine the Faraday constant. The valance of the hydrogen ions is z = 1. The molar mass n of the liberated hydrogen atoms is calculated using the laws of ideal gas on the basis of the volume V of the hydrogen collected at an external pressure p and room temperature T:

At the same time, the electric work W is measured which is expended for electrolysis at a constant voltage U0. The transported charge quantity is then
