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. ​ A.
