You prepare a 0.200M solution of a monoprotic buffer at pH 7.22.The pKa of this buffer is 7.53 at room temperature.
a. What is the molarity of the acid and conjugate base necessaryto make the buffer. [HA]=? [A-]=?
b. A separate 1.0 M stock solution of the acid and conjugatebase is made/ How many mL of each will you use to prepare 1.0 L ofthe buffer in part a? mL of HA=? mL of A-=?
c. You add 29mL of 2.3 M NaOH to your 1.0L of buffer. Is thebuffer capacity able to adequately handle this new addition ofNaOH? What will be your new pH?
