Determination of Faraday's constant

Product No: P3062101

Principle

Faraday's laws of electrolysis describe the correlation between the amounts of substances transformed in the reactions at the electrodes and the charge applied (amount of electricity). Faraday's constant, which appears as a proportionality factor, can be determined experimentally from the dependence.

Tasks

Determine Faraday's constant from the dependence of the volumes of hydrogen and oxygen envolved on the charge applied in the hydrolysis of dilute sulphuric acid.
