Organic acids

Organic acids are different from general acids. Here is all details about organic acids . The strength of organic acids and factors affecting their strength . As we promise we uploads it. We will also upload more presentations about general and organic chemistry botany and zoology. Our aim is to make knowledge accessible to each and everyone.

2. Organic Acids Organic acids are acids that has a carbon skeleton. Organic compounds with acidic properties. Organic acids partially dissociate in neutral aqueous solution and are generally considered as weak acids. The three major types of B ronsted-Lowery acids are Carboxylic acids, Phenol and alcohols.

3. 1)Carboxylic Acids: Carboxylic acids are the most common and most acidic organic compounds. Much stronger acids then water, alcohols and phenols.

4. 2) Phenols Phenols are more acidic than alcohols but less acidic than carboxylic acid. phenol pKa value is 10 -10 . Benzene ring is electron with drawing , so it will stabilize the phenoxide ion.

5. 3.Alcohols Alcohols are acidic in nature because it provide hydrogen ion but it is very less acidic pka value =10 16 to 10 18 Less acidic than water (10 7 ). -R group is electron donating group so it will destabilize the alkoxide ion. R-OH + H 2 O R-O - + H 3 O +.

6. Applications of organic acids Many of carboxylic acid are of immense importance because of their uses in food and beverage ,industries along with drugs and other manufacturing processes. Most common organic acid which are used in such manufacturing are azeliac acid, fumeric acid, malic acid, oxalic acid, tartaric acid and sebacic acid; Saturated long chain of monocarboxylic acid are basically fatty acids. The organic acid are utilized in plastic making, textiles, paper, metals, pharmaceutical, food industries as well as in manufacturing of cosmetics.

7. Also used in manufacturing of perfume , herbal insecticides, color and dyes and common household cleaners. Propionic acid are used in organic synthesis, used as various fungicides and also as food preserving chemical. Lactic acid is used in adhesive, plastic and textile. Glycolic acids are used in leather, textile electroplating, and metal cleaning industries. Citric and oxalic acids are used as rust removal. As acids, they can dissolve they iron oxides .

8. Organic acids are also used in food preservation because of their effects on bacteria. Oxalic acid as used to clean iron and also used as a bleach for wood, removing black stains caused by dissolved iron that binds to the wood during water penetration. Tartaric acid is a white crystalline organic acid which occurs naturally in many plants particularly in grapes, bananas and tamarinds. Also found in wine.

9. Many of organic acids are found in living things : ACIDS ORIGIN Citric acid Citrus fruits like orange and lemons. Tartaric acid Fruits like grapes and tamarinds. Ascorbic acid Present in citrus fruits as vitamins C. Formic acid The sting of nettle and ants. Oxalic acid The juice of tomatoes. Lactic acids When milk goes sour.
