carboxylic acid react with water

The solubility of carboxylic acids in water is similar to that of alcohols, aldehydes, and ketones.
Acids with fewer than about five carbons dissolve in water; those with a higher molecular weight are insoluble owing to the larger hydrocarbon portion, which is hydrophobic.

What is formed when a carboxylic acid is dissolved in water?

an acid-base equilibrium occurs: the carboxylic acid donates a proton to H2O, forming its conjugate base, a carboxylate anion, and water gains a proton, forming its conjugate acid, H3O+.

What happens to a carboxyl group in water?

The carboxyl group readily engages in hydrogen bonding with water molecules (Figure 15.3. 1).
The acids with one to four carbon atoms are completely miscible with water.
Solubility decreases as the carbon chain length increases because dipole forces become less important and dispersion forces become more predominant.

Is COOH soluble in water?

Carboxylic acid can dissolve in either water or an organic solvent such as ethanol.
It is also important to know that carboxylic acid can form salts with metals such as sodium or potassium.

Carboxylic acid dissolve in water to form a carbonic acid and a hydronium ion. As the reaction proceeds, the equilibrium shifts from the left side to the right side, until all of the reactants are consumed and no more reactant molecules remain.
