A 15.0-mL sample of a H3PO4 solution is titrated with a 1.00 M
NaOH solution. The neutralization reaction is complete when 33.6 mL
of NaOH is added. What is the concentration of the H3PO4 solution
(in M)?
A 350 mL buffer solution containing 0.15 M HF and 0.150 M NaF is
reacted with sodium hydroxide. What mass of NaOH can this buffer
neutralize before the pH rises above 4.0? If the same volume of
buffer was 0.35 M in HF and 0.35 M in NaF then what mass of NaOH
could be handled before the pH rises above 4.0?
