Titration Lab: NaOH with Standardized solution of KHP

Aim To standardize a sodium hydroxide (NaOH) solution against a primary standard acid [Potassium Hydrogen Phthalate (KHP)] using phenolphthalein as an indicator. Variables Independent variables Mass of KHP (mKHP) Volume of KHP solution Dependent variables Volume of NaOH added [since the colour change will not happen at exactly the same volume of NaOH added (VNaOH)]…
