karboksinaattiioni

Karboksinaattiioni refers to the anion formed when a carboxylic acid loses a proton. Carboxylic acids are organic compounds containing a carboxyl group (-COOH). This group consists of a carbonyl group (C=O) bonded to a hydroxyl group (-OH). When a carboxylic acid dissociates in solution, it typically releases a hydrogen ion (H+) from the hydroxyl group, resulting in the formation of the carboxylate anion (-COO-) and a hydrogen ion.

The carboxylate anion is resonance-stabilized. The negative charge is delocalized across both oxygen atoms within the carboxylate group. This delocalization makes the carboxylate anion a relatively stable species, contributing to the acidity of carboxylic acids. The conjugate base of a carboxylic acid is its corresponding carboxylate anion. For example, acetic acid (CH3COOH) dissociates to form the acetate anion (CH3COO-) and a proton. The properties of karboksinaattiioni vary depending on the specific organic group attached to the carboxylate moiety, influencing factors such as solubility and reactivity. Karboksinaattiioni are found in many salts and are important in various chemical and biological processes.
