Kelly is trying to make a buffer. The chemicals she has available are sulfuric acid, potassium sulfate, sodium bisulfate, acetic acid, hydrochloric acid, sodium chloride, sodium hydroxide, lithium acetate, and nitric acid. Her teacher tells her she can make two buffer systems. A) What are the two buffer systems she can make? B) Using the internet, find the pKa for both of these systems when you have a 50/50 mix of acid to conjugate base. C) Which of these buffers is more acidic? D) What prevents her from making a buffer out of the remaining chemicals? Kelly is trying to make a buffer.
