I recently looked at a reaction where CO is synthesized using formic acid and sulfuric acid, which seems to be one of the easier to control reactions for this, and obviously ventilation etc is necessary.
However I was wondering, is ventilation only necessary because of the dangerous nature of CO, or also because of the vapors or formic and sulfuric acid? I was quite into chemistry in school and after, but I do not remember that much, so I feel like I should know this but I cannot recall anymore. So at room temperature, if you would take a small amount of each of these acids and keep them either separately or mixed together, how fast/how much would evaporate and create dangerous acid vapor?
