Additional Problem: A buffer is
being prepared by adding HCl to pyridine (C5H5N,
see Appendix G for pKa of conjugate acid). It is desired to make a buffer at pH = 5.76
by adding 1.00 M HCl to a 250 mL
volumetric flask containing 1.720 g of pyridine. Determine the volume of HCl
that is needed to add to the volumetric flask which will be diluted to the mark
to make the buffer.
