Experiment 7, Analysis of KHP by titration with NaOH Wright College, Department of Physical Science and Engineering In this experiment, you will determine the amount (percent) of potassium hydrogen phthalate (KHP) that is in an impure sample. You will determine the percent of KHP via titration using NOH with known inolarity. The reaction will follow, KHCgH00, (aq) + NaOH (aq) ---------> KNaCHO, (aq) + H20 (I) At the end point, the...

A volume of 20.05 mL of NaOH was used to titrate a 0.45 g sample of potassium hydrogen phthalate (KHP), a monoprotic acid, which has a molecular weight of 204.2 g/mol. Calculate the molarity of the NaOH solution. For the above titration of potassium hydrogen phthalate with NaOH, if you have the following pH indicators: methyl red, bromothymol blue, and phenolphthalein, which indicator should you use? Explain why.
