The acid/base titration with NaOH and acetic acid is the oldest
experiment in the book. I did it when I was in college (a long
time ago) and both schools for which I work do the lab. I know
they repeat it in higher level classes with a few more steps to
make it more challenging. So it is to your advantage to try to
master it at this level so you can handle more detail when they
throw it at you. Part I: Standardization of a base (NaOH) Why
would you standardize a solution? Generally it is because you
need to precisely know the concentration of it. What variables
do you know in the first part? You know how many moles of acid
that you started with. (KHP). You can calculate moles of acid in
your starting material. You also know that the balanced chemical
equation for the neutralization of KHP and NaOH reacts in a 1:1
mole ratio between acid and base. KHP(aq) + NaOH(aq) → KNaP(aq)
+ H2O(l) With your buret, you measure the volume of NaOH
required to neutralize your KHP acid. You know the experiment is
complete when
