What is Tannic Acid?
Tannic Acid (C₇₆H₅₂O₄₆): Tannic acid is a natural organic compound found in many plants, fruits, and vegetables. It is a type of tannin, a class of astringent polyphenolic compounds. Tannic acid is extracted from gallnuts, oak bark, sumac berries, and other plant sources. It is used as an ingredient in food, beverages, and pharmaceuticals, and as a tanning agent in the leather industry. Tannic acid has astringent properties that make it useful for treating diarrhea, indigestion, and other gastrointestinal problems. It is also used as a gargle for treating sore throats. Tannic acid is also effective in treating hemorrhoids and other minor skin problems.
Types of Acidum Tannicum
Tannic acid a natural compound found in many plants, fruits and vegetables. It is a type of acid that can used to tan animal hides and produce leather. Tannins are a group of water-soluble compounds that found in many plants. Tannic acid is the most common tannin.
Properties of Tannic acid – C76H52O46
- Tannic acid is a type of organic acid that found in many plants, including oak trees. It has a number of properties that make it useful in a variety of applications.
- Tannic acid is a powerful antioxidant. This means that it can scavenge and neutralize harmful molecules called free radicals, which can damage cells and lead to disease.
- Tannic acid is also a chelating agent. This means that it can bind to metals and other minerals, making them less likely to cause damage to cells.
- Tannic acid is also a natural dye. It can used to color fabrics, food, and other substances.
- Finally, tannic acid has astringent properties. This means that it can shrink and tighten the skin, making it useful for treating skin conditions such as psoriasis and eczema.
Structure of Tannic acid (C76H52O46)
The tannic acid molecule is a large, complex molecule made up of 76 individual carbon atoms, 52 individual hydrogen atoms, and 46 individual oxygen atoms. The molecule arranged in a long, branching chain, with a large number of smaller oxygen and hydrogen atoms bonded to the carbon and hydrogen atoms in the chain. The tannic acid molecule is highly polar, with a large number of oxygen atoms and hydrogen atoms located on opposite ends of the molecule. This polarity makes the molecule very soluble in water.
Tests for Tannins
There are several tests that can used to determine the presence of tannins in a substance. One common test is the Folin-Ciocalteu assay, which uses a colorimetric assay to measure the amount of tannin in a sample. A second common test is the thiocyanate assay, which uses a spectrophotometric assay to measure the amount of tannin in a sample.
Alkaloid Precipitation of a Dibasic Salt
In the presence of a dibasic salt, an alkaloid will precipitate out of solution. This occurs because the alkaloid is a base and the dibasic salt is a strong acid. When the two combined, the base and the acid neutralize each other, resulting in the precipitation of the alkaloid.
Goldbeater’s Skin Test
- This is a test to see if you are allergic to goldbeater’s skin.
- Goldbeater’s skin is a type of collagen that used in some medical procedures. If you are allergic to goldbeater’s skin, you may experience a rash, hives, or difficulty breathing.
- If you are allergic to goldbeater’s skin, discontinue use and consult a doctor.
Ferric Chloride Test
The ferric chloride test a qualitative test used to determine the presence of iron in a substance. A solution of ferric chloride is added to the substance, and if iron is present, a red or yellow precipitate will form.
Tannic vs Tannin Acid
The terms “tannic” and “tannin acid” often used interchangeably, but they are not the same. Tannic acid a chemical compound that found in plants, while tannins a class of water-soluble polyphenolic compounds that found in plant tissues. Tannins what give tea and red wine their bitter taste. Tannins also responsible for the astringent feeling in the mouth.
Tannic Acid Uses
Tannic acid used in various industries. Some of its major applications include:
- In the leather industry, tannic acid used to tan hides and produce leather.
- The textile industry, tannic acid used to dye cloth.
- In the pharmaceutical industry, tannic acid used to make pills and tablets.
- The food industry, tannic acid used as a food additive to improve the color and also flavor of food products.
