Talk:Formic acid

Decomposition re-edit

The so called 'high' Hydrogen content of 55 g/L is not really high compared with methanol at 71 g/L or other hydrogen storage like methane, ammonia etc.

Flammability

Acetic Acid has the same NFPA pictogram but carries an additional GHS diamond for flammability. Why this discrepancy? 57.135.233.22 (talk) 20:10, 18 August 2023 (UTC)

It should. I added the flammability pictogram. Sandcherry (talk) 18:12, 21 March 2024 (UTC)

What does this mean?

"Formic acid is about ten times stronger than acetic acid" . Is this a pH thing? Or is it saying that formic acid would neutralise 10 times the amount of an alkali than acetic acid would? I am not a chemist. 78.146.94.150 (talk) 13:42, 19 March 2024 (UTC)

Hi! I just clarified the wording of this on the page.

To expand upon your question, if you had two containers of equal concentration of formic and acetic acids, the container with formic acid would have more free protons in it, or be more ready or quick to react. Neutralization ability doesn't tend to correlate with acid strength, however. As a simplified example, if you had 100 molecules of some alkali (or base) and 100 molecules of acetic acid, it would neutralize the base equally as well as formic acid, since ability to neutralize is more of a matter of ratio.

Off topic content

I'm not sure whether this is LLM generated, link Spam (for the one dubious reference included) or just misguided, but the content introduced in https://en.wikipedia.org/w/index.php?title=Formic_acid&diff=1280008163&oldid=1279555110 has little to no relevance for the article. I suggest for some editor to remove or revert this. ~2026-72200-3 (talk) 10:48, 2 February 2026 (UTC)
