Question

actually it has 2 parts:
1)balanced chemical formula for rxn with KHP and NaOH?
2)if the KHP was contaminated wiith NaCl, how would it affect the calculated normality of the NaOH?

Answer 1

KHP = Potassium Hydrogen Phthalate or KHC8H4O4.

KHC8H4O4 + NaOH --> KNaC8H4O4 + H2O

NV = N'V' gives N' = (NV)/V'

if the Normality of the KHP was high due to contamination with NaCl, the the calculated Normality of the NaOH would also be higher than actual.
