How Are Carboxylic Acids Soluble In Water

To know that are carboxylic acids soluble in water, it is necessary to know in the first instance what these compounds are, also to know about their characteristics, properties, and in what they are used.

What is a carboxylic acids

The carboxylic acids are chemical compounds that are characterized by presenting in their formation functional groups called carboxylic, these present a chemical structure -COOH, composed of one atom of carbon, two of oxygen, and one of hydrogen.

Know that are carboxylic acids soluble in water, requires knowing at least how these acids are chemically named, in other words, to know the nomenclature used to name them, with respect to this aspect, to name the carboxylic acids the word acid is placed followed by the name of the corresponding alkane, and the termination -o is replaced by -oic.

The carboxylic carbon is designated by 1 in the Aliphatic acids, listing the substituent which are attached to a main chain.

Among the fundamental characteristics of a carboxylic group is a C=O bond which is formed from a carbon Sp2, has a negative area around the carbonyl oxygen, and a positive area around the hydrogen in the hydroxyl group.

The negative area is in the upper center of the molecule, where the oxygen atom has a double bond joining it to the carbon atom, and in the lower right part of the molecule is the positive area, where the hydrogen atom is with the oxygen, OH.

Are carboxylic acids soluble in water?

 To answer if are carboxylic acids soluble in water, we must know about their properties.

Properties of carboxylic acids

 The solubility of carboxylic acids in water depends on their molecular weight, since these acids form hydrogen bonds on contact with water. Carboxylic acids with small molecular weights are soluble in water, while as the length of their carbon chains increases, their solubility in water decreases.

 Compounds of the sodium and potassium salts type present a high water soluble character, not in vain they are used as ingredients in soaps, the first four of the aliphatic monocarboxylic acids are liquid and highly soluble in water, from dodecanoic acid or lauric acid onwards the carboxylic acids present a solid state and are not soluble in water.

 In this way, it is stated that carboxylic acids that present a number greater than ten carbon atoms are not soluble in water.

These carboxylic acids have higher boiling points than aldehydes, alcohols and ketones, which have equal molecular weights, and their boiling point is the product of the dimer stably formed by hydrogen bonds.

 The melting points of the carboxylic acids that have double bonds in their chains are lower, and vary depending on the number of carbon atoms they possess.

 In which carboxylic acids are used

 Depending on whether are carboxylic acids soluble in water or not, they have various applications, such as at industrial level, for example acetic acid is used in the production of vinyl to manufacture polymers.

 The use of carboxylic acids includes the production of herbicides, plasticizers, in the perfume industry, in the food industry they are used as preservatives for jams, soft drinks, and fruit juices.

 They are also used in the manufacture of medicines, where they are used for the synthesis of insulin Wait with novel processes, their use as colorants, pesticides, in the production of varnishes, polyester, etc.

 Specifically, formic acid is used in livestock for dairy production, where treatments are performed with this acid to cows, with these processes to increase milk yield in the winter seasons, and improve the quality of feed for cattle.

 Are carboxylic acids soluble in water, and if they are not, they also have specific uses, and the company ECHEMI presents a varied availability in carboxylic acids such as:

Carboxylic acids are used to produce solvents for resins, photographic films, lacquers, as a mordant in dyeing, in saddlery it is used in leather softening, in this industry carboxylic acids replace inorganic acids to achieve better performance in products such as bleaching, depilation, leather, to neutralize the lime used in the tanning process of these, and in order to prevent the formation of mold on wet leather.
