How to quickly make 9% vinegar from 70% acetic acid?

It is very easy to make 9% vinegar from 70% acetic acid. You need to dilute 2 tablespoons of essence in a glass of water. Many housewives deliberately buy only concentrate, forever refusing to use table vinegar. After all, knowing the correct proportions, you can get acetic acid of any strength from one bottle - from 3 to 69%.

How to properly dilute acetic acid?

2 tablespoons per glass is the approximate proportion of essence and water. Glasses come in different sizes. If the recipe requires high precision, use the proportion: 1 ml acetic acid and 6.8 ml water.

Subtleties of preparing the solution:

• Any water will do. The acid has disinfecting properties. Therefore, you can safely dilute vinegar with raw water. If there are any microbes in it, they will die in an acidic environment.
• Use a kitchen scale for accurate measurements. To get the correct 9% solution, weigh the required amount of ml of essence, multiply the resulting figure by 6.8. This is exactly the amount of water you need to add.
• Measure vinegar and water using spoons. If you don’t have kitchen scales at home, good old spoons will help (table spoons or tea spoons, depending on how much solution you need to get). Just add 1 tablespoon of acid to the glass, then 7 tablespoons of water.

To obtain 1 liter of 9% vinegar, you need to mix 880 ml of water and 120 ml of 70% essence.

Can the solution be stored?

Acetic acid is a known preservative.Thanks to it, the preparations stay in jars all winter and do not spoil. So why not store essence water? If 9% vinegar is used frequently, you can dilute 70% acid for future use.

Follow the storage rules:

• Use a glass container or, in extreme cases, a plastic container. Metal containers are not suitable for storing acidic solutions.
• Close the bottle tightly with the cap. The issue of tightness is very important. If the lid allows air to pass through, the liquid will gradually evaporate.
• Store the solution in the refrigerator, pantry, or kitchen counter. The main thing is that the temperature does not go beyond -3 to +35 °C.
• If a kitchen cabinet is used, it is important that it is located away from the stove.
• The vinegar solution must be protected from direct sunlight. Simply storing it on the table is wrong.
• The shelf life of the solution is approximately 24 months. You need to count from the date of manufacture indicated on the bottle.

If you often make a 9% vinegar solution from acid, mark the required level of water and vinegar on the container with a marker. Now, to dilute, you don’t have to weigh anything - you can navigate by the marks.

Where to use?

Few people know that vinegar and vinegar solution are far from the same thing. The first is a natural product obtained from the fermentation of wine. It has a mild taste and is used mainly in the preparation of various dishes: sauces, drinks, soups (gazpacho and others), desserts.

A solution of acetic acid, which, in turn, is produced synthetically, is often sold under the guise of table vinegar. “Chemistry” does a better job of disinfecting and preserving vegetables for the winter. In this case, the solution can also be used in cooking, for example, to extinguish soda.

By diluting the essence yourself, you essentially get the same product as 9% table vinegar. And even a little more. The fact is that recently cases of falsification have become more frequent. Manufacturers dilute vinegar with more water than necessary. The result is a 4–6% solution instead of a 9% solution. Housewives use it for preservation, and then the jars unexpectedly explode. It turns out that diluting acetic acid with water yourself is even more reliable than buying finished products.
