The titration of an impure sample of KHP found that 36.00 mL of 0.100 M NaOH was required to react completely with 0.758 g of sample. What is the percentage of KHP in this sample? KHP: Potassium Hydrogen Phthalate; It is donating one H in an aqueous medium and react with NaOH. Its molecular formula is KHC2H404 (Hint: first write the balanced chemical equation for the neutralization of KHP with NaOH). Show your calculation to get the correct final...
