## What is this substance?

Acetic acid has the formula CH3COOH , which combines it with a number of fatty carboxylic acids. The presence of a carboxyl group (COOH) denotes monobasic acid. The substance is found in the world in organic form and is obtained artificially in laboratories. Acid is the simplest, but no less important representative of its series, easily soluble in water, hygroscopic.

The physical properties of acetic acid and the density vary depending on the temperature regime. At room temperature at 20 aboutC acid is in liquid state, its density is 1.05 g / cm3. Has a specific odor and sour taste. The solution of the substance without impurities hardens at a temperature below 17 and passes into crystalsaboutC. The process of boiling acetic acid begins at a temperature higher than 117aboutC. The methyl group (CH3) is obtained from the interaction of alcohol with oxygen of the acetic acid formula: fermentation of alcohol substances and carbohydrates, souring of wines.

### A bit of history

Vinegar was the first acid in the series to be discover and done in phases. Initially, acetic acid distilled from the 8th century began to be extracted by Arab scientists. However, even in ancient Rome, this substance, derived from sour wine, was use as a universal sauce. The name in Ancient Greek translates as “sour”. In the 17th century, scientists in Europe managed to extract the pure substance of the substance. At that time, he obtained the formula and found an unusual ability – acetic acid in the steam state was ignited by blue fire.

Until the 19th century, scientists discovered the presence of acetic acid only in organic form – as part of compounds of salts and esters. In the composition of plants and their fruits: apples, grapes In the body of humans and animals: sweat secretion, bile At the beginning of the 20th century, Russian scientists accidentally extracted acetic aldehyde from the reaction of acetylene with mercury oxide. To date, the consumption of acetic acid is so great that its main production is only largely synthetically.

### withdrawal methods

Whether pure acetic acid or with the presence of impurities in the solution depends on the method of extraction. Edible acetic acid is obtain by a biochemical method in the process of ethanol fermentation. In industry, several methods of extracting acid are isolated. As a rule, reactions with a high temperature and with the presence of a catalyst:

• Methanol (carbonylation) in reaction with carbon.
• Oxidation of the oil fraction with oxygen
• pyrolysis of wood
• Acetaldehyde oxidation with oxygen

The industrial way is more efficient and economical than the biochemical one. Thanks to the industrial method, the volume of production of acetic acid has increased hundreds of times in the 20th and 21st centuries, compared to the 19th century. To date, the synthesis of acetic acid by carbonation of methanol gives more than 50% of the total amount produced.

## Physical properties of acetic acid and its effect on the indicator

In the liquid state, acetic acid is colorless. Acidity levels of pH 2,4 are easily tested with a litmus test. When acetic acid stains the indicator, it is red. The physical properties of acetic acid vary widely. When the temperature drops below 16 about C, the substance takes on a solid form and resembles small ice crystals. It readily dissolves in water and interacts with a wide range of solvents, except hydrogen sulfide. Acetic acid reduces the total volume of the liquid when diluted with water. Describe independently the physical properties of acetic acid, its color and consistency, which you see in the following figure.

The physical properties of acetic acid as an electrolyte in reactions weaken. The permittivity is 6.15 at room temperature. Pressure, such as density, – Variable physical value of acetic acid at a pressure of 40 mm Hg. Art. And at a temperature of about 42C the boiling process will begin but already under a pressure of 100 mm. Hg. Art. Boiling occurs only at 62 about

## Chemical Properties

Reaction with metals and oxides, the substance shows its acid properties. Excellent dissolve a more complex compounds, acid forms salts which:. Magnesium, potassium acetate is called lead, etc. The pK value of the acid is 4.75.

When interacting with gases, vinegar enterssubstitution reaction with the subsequent displacement and formation of more complex acids: chloroacetic, iodoacetic. Dissolving in water, the acid dissociates with the release of acetate ions and hydrogen protons. The degree of dissolution is 0.4 percent.

The physical and chemical properties of acetic acid in a crystalline form form diamonds on hydrogen bonds. In addition, its properties are needed when creating more complex fatty acid, steroid and sterol biosynthesis.

## Lab Test

Detect acetic acid in solution to account for the identification of its physical properties, for example odor. It is enough to add a strong acid to the solution, which will begin to displace the vinegar salt with the release of its vapors. By laboratory distillation of CH3COA and H2SO4 it is possible to obtain acetic acid in dry form.

We will draw experience from the school program on Chemistry 8 class. The physical properties of acetic acid clearly demonstrate the chemical reaction of dissolution. It is enough to add copper oxide to the solution of the substance and lightly heat it. The oxide forms a completely soluble colored solution.

### derivatives agents

Qualified reactions of the substance with manysolution forms: esters, amides and salts. However, during the manufacture of other substances, the requirements for the physical properties of acetic acid remain high. It should always have high dissolution, and therefore, no third party impurities.

Depending on the concentration of acetic acidaqueous solution, many of its derivatives differ. The concentration of the substance more than 96% bears the name – glacial acetic acid. Acetic acid in 70-80% can be purchased at grocery stores, where it will be called – acetic essence. Table vinegar has a concentration of 3-9%.

### Acetic acid and everyday life

In addition to food characteristics, acetic acid has a number of physical properties, thanks to which mankind has found its application in everyday life. A solution of a substance of low concentration easily removes plaque from the surface of metal products, mirrors and windows. The ability to absorb moisture also plays a good role. Vinegar well removes odors in heat premises, removes stains from vegetables and fruits on clothes.

As it turned out, the physical property of acetic acid – to remove fat from the surface – can find application in folk medicine and cosmetology. A emollient solution of edible vinegar is rubbed with hairs to give them shine. The substance is widely use to treat colds, remove gums and skin fungus. The use of vinegar as part of cosmetic wraps to fight cellulite is gaining momentum.
