Editing Formic acid (section)

===Decomposition===
Formic acid readily decomposes by dehydration in the presence of concentrated [[sulfuric acid]] to form [[carbon monoxide]] and water:
:HCO<sub>2</sub>H → H<sub>2</sub>O + CO

Treatment of formic acid with sulfuric acid is a convenient laboratory source of CO.<ref name="koch">{{cite journal |doi=10.15227/orgsyn.044.0001 |title=1-Adamantanecarboxylic Acid |journal=Organic Syntheses |date=1964 |volume=44 |page=1|first1=H.|last1=Koch|first2=W.|last2=Haaf }}</ref><ref name="coleman">{{OrgSynth|title=''p''-Tolualdehyde|author=Coleman, G.

In the presence of [[platinum]], it decomposes with a release of [[hydrogen]] and [[carbon dioxide]].
:HCO<sub>2</sub>H → H<sub>2</sub> + CO<sub>2</sub>
Soluble [[ruthenium]] catalysts are also effective for producing carbon monoxide-free hydrogen.<ref name="Fellay2008">{{cite journal |doi=10.1002/anie.200800320 |pmid=18393267 |title=A Viable Hydrogen-Storage System Based on Selective Formic Acid Decomposition with a Ruthenium Catalyst |journal=Angewandte Chemie International Edition |volume=47 |issue=21 |year=2008 |last1=Fellay |first1=Céline |last2=Dyson |first2=Paul J. |last3=Laurenczy |first3=Gábor |pages=3966–8}}</ref>
