Aspirin (acetylsalicylic acid, ) is a weak monoprotic acid. To determine its acid-dissociation constant, a student dissolved 2.00g  of aspirin in 0.600 L of water and measured the pH. What was the Ka value calculated by the student if the  of the solution was 2.62?


A 0.100M  solution of ethylamine () has a pH of 11.87. Calculate the Kb for ethylamine.
