1) Use the Henderson-Hasselbalch equation to calculate the pH of
a buffer solution prepared by mixing equal volumes of 0.230 M
NaHCO3 and 9.00×10−2 M Na2CO3. (use Ka values given on
Wiki)
2) A volume of 100 mL of a 0.440 M HNO3 solution is
titrated with 0.440 M KOH. Calculate the volume of KOH
required to reach the equivalence point.
Use the Henderson-Hasselbach equation to calculate the pH of
each solution:
I figured out part A by myself because the numbers were already
in Molarity for me so I just plugged in numbers and calculated.
B. A solution that contains 0.785% C5H5N by mass and 0.985%
C5H5NHCl by mass. (Here, I don't know what to do with the %'s to
get the molarity in order to find the pH.)
C. A solution that contains 15.0 g of HF and 25.0...
Use the Henderson-Hasselbalch equation to perform the following
calculation. Calculate the mass of solid sodium acetate required to
mix with 100.0 mL of 0.10 M acetic acid to prepare a pH 4 buffer.
(Ka=1.8x10^-5 for acetic acid)
