Titration of a Saturated Potassium Hydrogen Tartrate (KHT) Solution Against Standardized NaOH Preparation of the Saturated KHT Solution for Titration 1. 1 100-mL graduated cylinder (washed and rinsed with distilled water) Aim To standardize a sodium hydroxide (NaOH) solution against a primary standard acid [Potassium Hydrogen Phthalate (KHP)] using phenolphthalein as an indicator.
