carboxylic acid
Alcohols may be oxidized to give aldehydes, ketones, and carboxylic acids. The oxidation of organic compounds generally increases the number of bonds from carbon to oxygen, and it may decrease the number of bonds to hydrogen.
Carboxylic acids with fewer than five carbon atoms are generally soluble in water, but those with higher molecular weight become insoluble due to their large, hydrophobic hydrocarbon chains.1
To increase the water solubility of these acids, you can convert them into their corresponding sodium, ammonium, or potassium salts. This process is effectively achieved by adding a strong base, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH). By transforming the carboxylic acid into a salt, the compound becomes significantly more soluble in aqueous environments.1
