Question

Name the method that is used to collect hydrogen prepared by electrolysis of acidified water.​

Answer 1

Electrolysis involves using electricity to break down electrolytes to form elements. The products of electrolysis can be predicted for a given electrolyte. Hydrogen can be purified using electrolysis.Acidified water is used for two reasons. Firstly, the ions provided by the acid greatly increase the electrical conductivity of the water, and this allows the decomposition of water to occur at a much increased rate. Secondly, the acid provides H+ions, which react, forming hydrogen, at the cathode.
