Is acetic acid a strong acid?

In this short article, we will answer the question “Is acetic acid a strong acid?” and will show you the uses of this acid in culinary and in the kitchen.

Is acetic acid a strong acid?

No, acetic acid is a weak acid.

Acetic acid: what is it?

Vinegar’s major component is acetic acid. The smell of this colourless acid is strongly sour. Vinegar comes in a wide variety of varieties, including rice vinegar, balsamic vinegar, rice vinegar, red and white wine vinegar, and apple cider vinegar. 

A variety of vinegar contains acetic acid in varying amounts. For instance, while the EU guideline for wine vinegar is 6 per cent, apple cider vinegar has 5 to 6 per cent acetic acid. 

Table vinegar, which is used to season food, typically has an acetic acid concentration of 4 to 8 per cent, whereas pickling vinegar can have an acetic acid concentration of up to 12 per cent.

What function does vinegar (acetic acid) serve in the culinary?

Since ancient times, vinegar has been used as a condiment to enhance flavour and preserve food. There are many different kinds of vinegar, usually identified by the component that serves as the basis. Additionally, there is vinegar flavoured with fruits, flowers, or herbs.

White wine vinegar, red wine vinegar, apple cider vinegar (also known as cider vinegar), balsamic vinegar, rice vinegar, and distilled white vinegar are the most popular varieties of vinegar. 

Vinegar is simply a mild acid diluted in water. It is typically made by fermenting bacteria using alcohol exposed to oxygen.

Add flavour 

Food tastes fresher when it has a little acidity. In addition, vinegar can provide sweet, buttery, malty, and spicy flavours as well as scents of wood from ageing in wooden barrels, depending on the variety.

Modify the food’s colour

Foods like apples and potatoes that turn dark when cut retain their colour thanks to vinegar. Additionally, it brings out the colour of fruits and vegetables that include anthocyanin pigment, such as cherries, red cabbage, eggplant, blueberries, etc. 

Under alkaline conditions, this pigment turns bluish; yet, under acidic ones, it keeps its reddish hue. In addition, dark plants like broccoli, cabbage, and other similar veggies have a yellow hue because of the acid in the vinegar.

Denaturation of proteins

The structure of uncooked meat is destroyed by acids like the acetic acid in vinegar and the citrus acid in lemon juice. Denaturing is the technique used to prepare ceviche.

Clotting proteins

When vinegar is added to fresh milk, the milk’s casein proteins coagulate to produce curds. This method is used to make some cheeses, including mascarpone and cottage cheese.

Decreases the stickiness of pasta 

Cooking pasta in acidic water releases less starch than cooking it in alkaline water, which is why adding a tablespoon of vinegar to the water makes the water less sticky. 

When adding pasta to a salad, when stickiness is undesirable, this is helpful. The acidity of the salad dressing blends with the flavour of the vinegar.

Egg whites 

Adding roughly 1/8 teaspoon of vinegar per egg white causes the proteins to break down, resulting in an increase in volume and silky, sparkling snow whites.

Clean the food

Vinegar can be a terrific ally in the battle against food contamination, especially if you’re not used to purchasing organic items like fruits and salad greens. Remainings from fertilizer-related goods are easier to get rid of with vinegar.


Cleaning the dishwasher’s water tanks and reducing odours can be accomplished by running an empty cycle with a cup of vinegar in the bottom.

What function does vinegar serve in the kitchen?

Much more than salad! The main uses of vinegar as food are to season salads and vegetables. However, it is capable of much more and can be very helpfully used to clean various household items, remove stains, and even aid unclog pipes.

Vinegar with white alcohol is most frequently used for cleaning. For instance, it can be employed as a potent anti-mould. To do this, combine one litre of water with fifty millilitres of sanitary water, then pour it over the mould. 

Apply a water and vinegar solution after it has dried. It is perfect for cleaning equipment, especially those in the kitchen because it is a wonderful degreaser. The recipe is very straightforward: just mix it with water until it dissolves. 

For cleaning purposes, two glasses can be added to washing machines and dishwashers during one cycle with the machine empty. A potent drain cleaner can be made by combining a cup of vinegar with refined salt, baking soda, and half a cup. 

After pouring the mixture into the sink or drain, add hot water. Baking soda and vinegar are other combinations that work well for polishing chrome objects. When combined, the two components are ideal for polishing metals and getting rid of rust. 

Do not, however, apply to surfaces made of granite and marble.
