salicylic acid and acetic anhydride. In the reaction the hydroxyl group on the benzene ring in salicylic acid reacted with acetic anhydride to form an ester functional group. This method of forming acetylsalicylic acid is an esterification reaction. Since this esterification reaction is not spontaneous‚ sulfuric acid was used as a catalyst to initiate the reaction. After the reaction was complete some unreacted acetic anhydride and salicylic acid was still be present in the solution as well as some

Criticism of selective exposure Although empirical evidence of selective exposure has been documented in countless studies conducted in a wide range of research area‚ there have also been plentiful reports of lack of evidence supporting the existence of selective exposure. For instance‚ in a study conducted by Feather (1962)‚ evidence of the effect of selective exposure on participants’ choices was not found. In specific‚ smokers and non-smoker participants did not display any significant preference

constant and purity. The ester was converted to salicylic acid by base hydrolysis. The products were refluxed and recrystallized‚ to ensure maximum purity‚ and filtered‚ dried‚ and weighed. The melting point of the product was determined using a Fischer-Johns melting point apparatus. The acid then dissolved in separate beakers with 95% ethanol and water and titrated with 0.050 M NaOH‚ previously standardized with potassium hydrogen phthalate‚ through potentiometric titration.
