Assume that you mixed 20.00 mL of 0.040 M KI with 20.00 mL of
0.060 M (NH4)2S2O8 , 10.00 mL of 0.00070 M Na2S2O3 , and a few
drops of starch. The point of mixing sets time = 0.
The Initial Concentrations are:
[KI] = 0.016M
[(NH4)2S2O8] = 0.024M
[Na2S2O3] = 0.00014M
Oxidation-Reduction Reaction between iodide and peroxydisulfate:
2I- + S2O8^2- -> 2SO4^2- + I2
Iodine Clock Method reaction: 2S2O3^2- +I2 -> 2I^- +

A 360.0 −mL buffer solution is 0.170 M in HF and 0.170 M in
NaF.
A) What mass of NaOH could this buffer neutralize before the pH
rises above 4.00?
B) If the same volume of the buffer was 0.360 M in HF and 0.360
M in NaF, what mass of NaOH could be handled before the pH rises
above 4.00? I keep getting 1.8 g and 3.5 g, which is wrong.
