Title: Determining the concentration of gases
Post by: Boruto on April 05, 2021, 12:13:25 PM

Hello everyone,,
How can i determine the concentration of gases such as Hydrogen Sulfide (H2S), Nitrogen Dioxide(NO2), Carbon Dioxide(CO2), Sulfur Dioxide(SO2)?? Can it be done by titration i.e. volumetric analysis or is there any other method to do so?

There a gas sensors in the market to detect directly digital. Of course you can absorb acidic gases like SO2, CO2, NO2, etc, on NaOH, CaO, etc. and do a back titration .
