INTRODUCTION: Carboxylic acids are organic acids characterized by the presence of a carboxyl group‚ -COOH. This acid acts as a weak acid‚ which can react with a strong base. Carboxylic acids form hydrogen bonds with many water molecules and are more soluble with one to four carbon atoms. Also‚ it may have an R group that consist of hydrogen or an alkyl group that changes its water solubility. Carboxylic acids with low molecular weight have odor at room temperature and higher molecular weight
