These are sometimes called "single displacement" reactions. 64 mL to L first. 1 mL of NaOH used 14. abbreviated as KHP, where "P" stands for the phthalate ion, C8H4O4 2-, not for phosphorus. forming a precipitate) while others will remain in solution, unchanged. Assume all reactions occur in aqueous solution. The balanced chemical equation for the reaction is: KHC8H4O4(aq) + NaOH (aq) => H2O(l) + KNaC8H4O4(aq) (1) KHP was chosen as a good acid to standardize NaOH because it has high molecular weight and stable on drying.
