Theoretical Foundations

Organic salts are compounds formed by the reaction between carboxylic acids and inorganic bases. This reaction is a neutralization, where the acid donates a proton (H+) and the base provides a hydroxide ion (OH-), resulting in the formation of water (H2O) and an organic salt.

Carboxylic acids are organic compounds that contain the carboxyl functional group (-COOH). They are weak acids but can react with strong bases to form salts. Common examples of carboxylic acids include acetic acid (CH3COOH) and citric acid (C6H8O7).

Inorganic bases, on the other hand, are compounds that can neutralize acids. Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH). When these bases react with carboxylic acids, organic salts such as sodium acetate (CH3COONa) and potassium citrate (K3C6H5O7) are formed.

Definitions and Concepts

Organic Salt: Compound resulting from the reaction between a carboxylic acid and an inorganic base.

Carboxylic Acid: Organic compound that contains the carboxyl functional group (-COOH).

Inorganic Base: Compound that can neutralize acids, usually containing a hydroxide ion (OH-).

Neutralization: Reaction between an acid and a base, resulting in the formation of salt and water.

Practical Applications

Organic salts have several important practical applications. In the food industry, salts such as sodium benzoate and calcium propionate are used as preservatives, inhibiting the growth of microorganisms that cause food spoilage.

In the pharmaceutical industry, salts such as sodium citrate are used as buffering agents to maintain the stability of the pH in medications. They are also used in intravenous solutions to correct electrolyte imbalances.

In cleaning products, salts such as sodium lauryl sulfate are used due to their emulsifying and foaming properties. These salts help disperse oils and fats, making it easier to remove dirt.

In the cosmetics industry, salts such as sodium stearate are used as emulsifiers in creams and lotions. They help mix ingredients that normally do not combine, such as water and oil, creating homogeneous and stable products.
