WebKHP reacts with NaOH as shown below. The stoichiometry of the reaction indicates that one mole of potassium hydrogen phthalate reacts with one mole of NaOH. The acidic solution of KHP is colorless when phenolphthalein indicator is added. When enough NaOH has been added to react stoichiometrically with the acid, the indicator in the solution will … WebHINTS: Molar mass is grams / moles. We have grams from the weighed mass, we can calculate moles of acid from the titration. Monoprotic means that it produces 1 H+ per molecule. This means that our moles of NaOH added and moles of acid are the same. You will need to use your concentration of NaOH from the previous question 3.
