Determining volume of hydrogen gas evolved in water splitting reaction?

21 February 2023 0 790 Report

I want to carry out a photocatalytic water spliting reaction. This reaction will generate hydrogen and oxygen gas in 2:1 ratio according to the following reaction -

2H2O + energy (light) → 2H2 + O2

So, if I collect the produced gas over water in a test tube, should I be able to determine the volume of hydrogen gas in that mixture? From literature, we can see gas chromatography is used to determine the volume and evolution rate of hydrogen. Is that necessary for a small lab experiment?
