Web9 de abr. de 2024 · Answer: Lower aliphatic amines are soluble in water because they can form hydrogen bonds with water molecules. Solubility decreases with increase in molar mass of amines due to increase in size of the hydrophobic alkyl part. Therefore, higher amines are insoluble in water. WebAmmonium salts of low molecular weight are soluble in water if the hydrocarbon portion of the amine is small. Because the nitrogen atom of an ammonium salt has a positive charge, ammonium salts are more water-soluble than amines. Drugs containing an amino group are often prepared as ammonium salts to improve their solubility in body fluids. WebCARBOXYLIC ACID Sour or tart taste.
