DESIGN YOUR OWN EXPERIMENT
As a future scientist, you have the opportunity to show your
laboratory skills by designing your own experiment. Below you will
be provided an experimental question. Your job will be to
physically complete an experiment to test the hypothesis associated
with your question. Once again, you must conduct the actual
experiment and document it. Use your Experimental Planning Form to
guide you through the experiment. Keep in mind the
overall goal is to conduct a valid...

The goal of this experiment is to prepare an aqueous solution of
sodium hydroxide and determine its concentration by titrating it
with a solution containing a precise mass of potassium hydrogen
phthalate KHC8H4O4 (abbreviated KHP). The reaction formula is:
NaOH(aq) + C8H5KO4(aq) → NaC8H4KO4(aq) + H2O(l). This indicates
that the ration of NaOH to KHP is 1:1 which means that 1mol KHP is
equal to 1 mol NaOH.

standardized solution...
