# Difference Between Acetic Acid and Glacial Acetic Acid

Here we are going to learn about the differences between Acetic Acid and Glacial Acetic Acid. However, before we get into the differences there are few things we should know. To start with, we will understand what acetic acid is first.

Well, acetic acid which is also known as ethanoic acid is a carboxylic acid composed of a carboxyl group. It is represented by the chemical formula $C_{2}H_{4}O_{2}$. Acetic acid is commonly found in plants and animal organisms. It can occur in either free state or in the form of esters and other compounds. It can also be prepared industrially.

On the other hand, glacial acetic acid is nothing but a pure or concentrated form of acetic acid. This acid is also called anhydrous acetic acid as it contains little amount of water. Glacial acetic acid is colorless and is very corrosive.

## Difference Between Acetic Acid and Glacial Acetic Acid

There is one main difference between acetic acid and glacial acetic acid and it has to do with the level of concentration of the acid. Acetic acid solutions usually has a high amount of water meaning it is is dilute form whereas glacial acetic acid has a very less percentage (almost 1 percent) of water. However, we will look at some of the other important differences between the two in the following table.

Difference Between Acetic Acid and Glacial Acetic Acid

Acetic acid

Glacial Acetic acid

Acetic acid is a solution of acetic acid and water.

Glacial acetic acid is nothing but the concentrated form of acetic acid solution.

Acetic acid contains more water and is in its diluted form.

Glacial acetic acid has less than 1% of water content and is concentrated.

Acetic acid causes no harm and is used as a food additive and it is found in household items like vinegar.

Glacial acetic acid is corrosive in nature and can cause injuries or irritation to the skin, eyes and nose.

Acetic acid cannot be frozen or form crystals.

Whereas, glacial acetic acid can form ice-like crystals.

Acetic acid is produced via rhodium-iodine catalyzed carbonylation of methanol.

Glacial acetic acid is obtained by dipping acetic acid solution in a “stalactite” of solid glacial acetic acid.

Acetic acid is naturally occuring and found in plants and animal organisms.

It is usually manufactured in a lab.
