You have available 1.00 L volumes of the three following
solutions: 1.00 M HCl, 1.00 M NaOH and 1.00 M NaH2PO4. You wish to
prepare 500.0 mL of a buffer solution that maintains a pH of 2.50.
Indicate which two of these three solutions you would use to
produce this buffer, and calculate the volume of each of these two
solution you would need to mix to get the desired volume and pH
value for the buffer.
