Popular questions
Is formic acid a strong acid?
No—formic acid is a weak acid in water (pKa ≈ 3.75), though concentrated solutions are corrosive.
What is formic acid used for?
As E236, it’s used mainly as an antimicrobial preservative and acidity regulator (especially in animal feed and silage), and outside food in leather/textile processing, rubber coagulation, beekeeping, and as a chemical intermediate.
What does formic acid smell like?
It has a sharp, pungent, vinegar-like odor that’s acrid and stingy (reminiscent of ant stings).
What does formic acid do to the body?
At low food-use levels it’s metabolized to formate and then to carbon dioxide, but concentrated exposure irritates and can burn skin, eyes, and airways; large ingestions may cause metabolic acidosis and systemic toxicity.
Does formic acid have hydrogen bonding?
Yes—its carboxyl group donates and accepts hydrogen bonds, often forming dimers, which contributes to its relatively high boiling point.
How do i clean my lexmark e238 printer head?
That refers to a Lexmark printer; here E238 means calcium formate, a food additive—not a printer—so please consult your printer’s manual or manufacturer support.
How do i clean my lexmark e238?

How to get calcium formate?
Purchase calcium formate (E238) from reputable chemical suppliers; for any food-related intent, choose food‑grade material with a certificate of analysis and verify it’s legally permitted for your intended use in your country.
How to make calcium formate?
It is produced industrially by neutralizing formic acid with calcium hydroxide or calcium carbonate and then crystallizing the salt; due to handling hazards and purity needs, consumers should buy certified food‑grade product rather than making it.
How to open up the back of the ink printer on a lexmark e238?
