Does Vinegar Evaporate? (All You Need to Know)

Vinegar is a regular component in our daily life because of its variety of uses. It is used in our kitchen for its aroma and taste. Vinegar is also used for cleaning and other purposes. Today, we are going to discuss whether vinegar evaporates or not.

Does vinegar evaporate?

Vinegar evaporates at room temperature, in the sun and when it is heated, cooked, and boiled. The main reason behind the evaporation of vinegar is its weak hydrogen bonds. It contains water and acetic acid as its core elements. These core elements fasten the evaporation of vinegar.

The chemical components of Vinegar are Acetic Acid (CH3COOH), Pyroligneous Acid, Sodium Acetate (C2H3NaO2), Bicarbonate of Soda (NaHCO3), and Cream Of Tartar (KC4H5O6). The key takeaway point from the components of Vinegar is that it has a lot of hydrogen bonds.

Vinegar evaporates over time because of its weak hydrogen bonds. The hydrogen bonds break and evaporate. As a result, we get water vapor and acetic acid vapor. The pure variety of vinegar evaporates fully.

On the other hand, white vinegar is made from milk, sugar, and potato. But the most common practice is making white vinegar by fermenting ethanol (grain alcohol). White vinegar also evaporates. White vinegar contains 5-7 % acetic acid (CH3COOH).

It also contains 94-96 % water. As white vinegar also has weak hydrogen bonds, it breaks and evaporates.

Another important fact about vinegar is that it evaporates without leaving any residue. When vinegar evaporates, it results in more concentrated vinegar. It does not even leave behind acetic acid as residue.

Does vinegar evaporate quickly?

Yes. Vinegar evaporates quickly. It evaporates quickly compared to other liquids possessing the same kind of chemical components. Vinegar having weak hydrogen bonds quickens the evaporation procedure quite significantly. If vinegar is left open, it evaporates completely.

How long does it take for vinegar to evaporate?

Vinegar takes different times to evaporate depending on the state and situation it is in. Let’s take a look at some of them:

At room temperature:

Sixty-eight to seventy-two degrees Fahrenheit (F) is considered room temperature. Vinegar evaporates at room temperature. At room temperature, vinegar evaporates after eighty minutes. So vinegar evaporates at a fast rate at room temperature.

You have to be careful about the fact that no added pressure is present at room temperature and vinegar evaporates without any hindrance.

In the sun:

It takes a long time for vinegar to evaporate under the sun. It can take as much as twenty-four hours for vinegar to evaporate under the natural light of the sun. Vinegar evaporates at a slow pace under the sun.

So if you want your vinegar to evaporate quickly, then placing it under the sun is not the right step.

When heated:

You can heat up vinegar in the microwave and eventually, vinegar will evaporate after heating. It will leave steam on the microwave window after it evaporates. Vinegar evaporates quickly when it is heated.

When cooking or boiling:

Vinegar evaporates when it is cooked or boiled. If you boil or cook vinegar, it starts losing acetic acid. The boiling point of acetic acid is two hundred and forty-four Fahrenheit (F) or one hundred and eighteen Celcius (C).

So vinegar evaporates at a fast rate when it is cooked or boiled.

So expect for in the sun, vinegar evaporates quite quickly and efficiently in other situations.

Can vinegar evaporate faster than water or olive oil?

Olive oil starts evaporating at room temperature. But vinegar evaporates faster than olive oil at room temperature.

It is because vinegar possesses a higher vapor pressure than olive oil. How fast a liquid evaporates often depends on the amount of vapor pressure it possesses.

The vapor pressure of Olive oil is 0.05 mm at 308° Celcius. On the other hand, the vapor pressure of Vinegar is 15.7 mm at 25 degrees Celcius.

Vinegar also evaporates faster than water. The chemical composition of water is H2O. It means water has strong hydrogen bonds. And the important thing here is that vinegar also has hydrogen bonds. But the hydrogen bonds of vinegar are not so strong as water.

The stronger the hydrogen bonds, the longer the evaporation process.

Does vinegar evaporate in water?

Vinegar does not evaporate in water. The components of vinegar are attracted to the components of water. That is why vinegar does not evaporate in water. Rather it gains the ability to mix itself with vinegar effortlessly. Both vinegar and water are polar elements.

Polar elements easily attract each other and make homogeneous mixtures.

At what temperature does vinegar evaporate?

There are different kinds of vinegar. Some of them are Distilled white vinegar, Apple cider vinegar, Balsamic vinegar, Red wine vinegar, Rice vinegar, Malt vinegar, Red rice vinegar, Champagne vinegar, Sherry vinegar, Black vinegar, Cane vinegar.

Besides, there are Beer vinegar, Raisin vinegar, and Apricot vinegar. But all the kinds of vinegar have the same evaporation temperature. Because all of them possess acetic acid and water as their core elements.

The boiling point of vinegar is one hundred and one degrees Celcius (C) or two hundred and fourteen Fahrenheit(F). So naturally, vinegar starts evaporating at this temperature. If you dilute the vinegar, then the boiling point will be similar to water.

Does vinegar evaporate completely or leave a residue when it dries?

Vinegar evaporates completely and does not leave any residue when it dries. After the evaporation process of vinegar is completed, you will get acetic acid and water vapor. But in the case of pure kind of vinegar, it does not leave any residue.

Even the smell of the vinegar evaporates completely. But the evaporation of the vinegar smell happens slowly. So even after the evaporation of vinegar, you will still get its smell for some time.

Vinegar is made of volatile liquids. Both water and acetic acid are volatile liquids. It means water and acetic evaporate at the same speed. It results in the complete evaporation of vinegar.

If the evaporation speed of water and acetic acid were not the same, the evaporation process would have been longer than usual.

What happens when vinegar is left open and exposed to air?

When vinegar is left open and exposed to air, bacteria starts to fiddle in the vinegar. But the important thing about these bacteria is that they are harmless. Even after vinegar gets infected with these bacteria, it is still usable.

These bacteria do not possess the power to affect the quality and flavor of vinegar. So it is a completely harmless bacteria in this sense.

This bacteria creates a cloudy texture inside vinegar. This cloudy texture is actually harmless cellulose. Cellulose is a kind of complex carbohydrate that has nothing to do with the quality and flavor of vinegar.

Does vinegar expire? How long does vinegar last when opened?

No. Vinegar does not expire. Vinegar can be stored for a lifetime. According to vinegar researchers, vinegar has a never-ending lifetime. Due to vinegar possessing acetic acid, it has a long lifetime. Vinegar does not even need to be stored.

Even after a bottle of vinegar is opened, its lifetime remains the same. This rule applies to all varieties of vinegar.

Only the distilled white kind of vinegar stays the same throughout its lifetime. Other kinds of vinegar may develop a cloudy texture in it. But this texture is totally harmless and can be used later to make more vinegar if needed.

Actually, this cloudy texture of vinegar is called mother vinegar. Mother vinegar is completely a normal part of vinegar. The mother vinegar can be separated to make more vinegar in the future.

How do you store white vinegar after opening?

After opening, white vinegar should be stored in a cool and dark place. You have to tightly seal the opening of the bottle after storing. If white vinegar is stored properly, it will not go bad for a long time.

You have to make sure that you keep your white vinegar away from heat and light.

White vinegar does not need to be refrigerated. To be sure if the white vinegar you have stored has gone bad or not, you can smell or taste the vinegar. If it tastes fresh, you can continue using it on a regular basis. If it tastes spoiled, throw it away immediately.

Final Thoughts

Vinegar evaporates completely without leaving any residue behind. After evaporation of vinegar, you will get acetic acid vapor and water evaporate. Even the smell of the vinegar evaporates over time. As vinegar evaporates quickly in any given situation, it should be stored properly.
