What is the Difference Between Methanoic Acid and Formic Acid? Explained

Have you ever heard of Methanoic acid and Formic acid? Surprisingly, they are the same compound! It’s just that Methanoic acid is the systematic name for organic acid, while Formic acid is the common name. Quite often, people get confused about whether they are different from each other or not. But now you don’t have to worry anymore because I will explain the difference between these two acids in a simple way.

Methanoic acid, as the name suggests, is derived from methane, whereas Formic acid is derived from formica (Latin for ant). Methanoic acid is found naturally in the venom of ants and some other insects. On the other hand, Formic acid can be found in certain plants, such as stinging nettles, and in the bodies of ants. Another distinction between the two is the molecular weight. Methanoic acid has a molecular weight of 46.02588 g/mol, while Formic acid has a molecular weight of 46.02548 g/mol. These may be minute differences, but it is valuable to differentiate them for scientific purposes.

Despite their differences, both Methanoic acid and Formic acid are used in different industries such as cosmetics, pharmaceuticals, and agriculture. They are also used as a food preservative. Moreover, Methanoic acid is commonly used in the preservation of animal specimens whereas Formic acid is used in leather tanning. Clearly, despite sharing identical chemical structures, Methanoic and Formic acids have different applications, and these acids are essential in different fields of industry. Now that you know the difference between Methanoic acid and Formic acid, you can sound like a professional chemist in your next conversation!

Chemical structure of methanoic acid and formic acid

Methanoic acid and formic acid are two naturally occurring organic compounds that have similar chemical structures. Methanoic acid is also known as formic acid, as its chemical name is derived from the Latin word for ants, Formica. These compounds are used in a variety of applications, including the production of textiles, leather, and rubber. Methanoic acid and formic acid are also used as preservatives in food, and formic acid is used as a pesticide.

  • Methanoic acid has the chemical formula HCOOH, and is a colorless liquid with a pungent odor. It has a boiling point of 100.8 degrees Celsius and a melting point of 8.4 degrees Celsius.
  • Formic acid has the chemical formula HCOOH as well, and is also a colorless liquid with a pungent odor. It has a boiling point of 100.8 degrees Celsius and a melting point of 8.4 degrees Celsius. The main difference between the two compounds is that methanoic acid is produced exclusively by oxidation of methyl alcohol, whereas formic acid is produced by oxidation of carbon monoxide.

Toxicity and safety concerns for methanoic acid and formic acid.

Both methanoic acid and formic acid are toxic and can be hazardous to human health. When these acids come into contact with skin or are inhaled, they can cause severe burns or even death. The differences in toxicity and safety between these two acids lie in their methods of interaction with the human body.

  • Methanoic Acid Toxicity: Methanoic acid is more toxic than formic acid. Ingestion of as little as 1 ml of methanoic acid can lead to severe symptoms such as difficulty in breathing, vomiting, and in severe cases, cardiac arrest. Contact with skin or inhalation of methanoic acid vapors can cause skin burns, respiratory issues, and permanent damage to the eyes. Methanoic acid has a low boiling point, so it evaporates easily, making inhalation a significant concern.
  • Formic Acid Toxicity: Formic acid is less toxic than methanoic acid. However, when exposed to large enough quantities, it can cause serious health concerns. Skin contact can lead to burns and eye damage, while inhalation of formic acid can cause respiratory problems. Ingesting formic acid can cause nausea, vomiting, and in extreme cases, even death.
  • Safety Concerns: Both acids should be handled with extreme caution. Direct contact with either acid can cause severe burns, eye damage, and respiratory problems. Proper safety equipment, such as gloves, protective clothing, and goggles, should be worn when handling these acids. Additionally, these acids should only be used in well-ventilated areas to reduce the risk of inhalation.

Difference in interaction:

The toxicity difference between methanoic acid and formic acid lies in the methods of their interaction with human bodies. Methanoic acid is highly volatile and easily absorbed through inhalation, exacerbating respiratory concerns. On the other hand, formic acid is not as volatile and is more likely to cause skin or eye damage upon direct contact.

Comparing the toxicity of Methanoic Acid and Formic acid

Acid LD50 (mg/kg) Symptoms
Methanoic Acid 250-2000 Vomiting, shortness of breath, cardiac arrest, skin burns, and eye damage.
Formic Acid 1400-3300 Ingesting formic acid can cause nausea, vomiting, and difficulty in breathing while skin and eye contact can cause burns or irritation.

It is evident from the table that methanoic acid is significantly more toxic than formic acid. The LD50 of methanoic acid is much lower than that of formic acid, indicating that even small quantities of methanoic acid can have a significant impact on human health.
